1. Kensington Expert Wireless Trackball Mouse – Best Overall Kensington Trackball
Kensington Expert Wireless Trackball Mouse
55mm optical tracking ball
Bluetooth LE and 2.4GHz
Four customizable buttons
Detachable ergonomic wrist rest
The Kensington Expert Wireless Trackball Mouse combines a large 55mm ball, familiar index-finger operation, and both Bluetooth LE and 2.4GHz wireless connections. Its 4.2 rating reflects a balanced design that serves general office work, editing, navigation, and multi-device users without the extreme height or unusual thumb positioning found in specialized trackballs.
Pros
- Large, smooth operating ball
- Flexible wireless connectivity
- Useful programmable controls
- Removable wrist support
- Broad platform compatibility
Cons
- No physical scroll ring
- Windows ARM currently unsupported

The Diamond Eye optical system gives the large ball a smooth, precise feel, while the patented scroll ring makes vertical navigation fast without shifting the hand away from the controls. A detachable wrist rest supports longer sessions, and the ambidextrous body accommodates either hand. KensingtonKonnect software allows users to customize the four buttons as well as scroll and cursor speed, making the mouse practical for shortcuts and productivity applications.
Connectivity is a major strength. The built-in Bluetooth LE is useful for pairing directly with a compatible computer, while the included USB dongle provides 2.4GHz connectivity. Automatic sleep and configurable power settings help preserve battery life. One limitation is the absence of a physical scroll ring in the supplied specification, so users who prefer a separate scrolling component may favor the Orbit models. Windows ARM-based computers are also not currently supported by the customization software.
This is the strongest general recommendation in the group because it combines a proven large-ball layout, wireless flexibility, useful programmability, and a removable support. It suits professionals who want precise control, a manageable desk footprint, and the freedom to move between laptop and desktop systems. For a first Kensington trackball, it offers the broadest balance of mainstream features.
Large-Ball Control and Comfort
The 55mm ball gives index-finger users a broad, smooth surface that can make small corrections and quick sweeps feel controlled. The detachable wrist rest adds palm support when desired, while the low desktop profile helps keep the setup uncluttered.
Wireless Flexibility and Customization
Bluetooth LE and the 2.4GHz USB dongle cover different connection preferences. KensingtonKonnect adds useful control over the four buttons, cursor speed, and scroll behavior, although Windows ARM users should review the stated software limitation.

2. Kensington SlimBlade Pro Wireless Trackball – Best Premium Kensington Trackball
Kensington SlimBlade Pro Wireless Trackball
55mm dual-sensor trackball
Bluetooth 2.4GHz wired
Rechargeable four-month battery
Eight programmable button sets
The Kensington SlimBlade Pro Wireless Trackball is the feature-rich option in this guide, carrying a 4.1 rating and a strong emphasis on flexible connectivity. It supports Bluetooth, 2.4GHz wireless, and wired use, making it appropriate for users who alternate among notebooks, desktop computers, and docking setups.
Pros
- Three connection methods
- Rechargeable battery system
- Highly programmable buttons
- Low-profile ambidextrous shape
- Precise dual-sensor tracking
Cons
- Higher feature complexity
- Windows ARM currently unsupported

Its 55mm ball is monitored by dual sensors for accurate and responsive cursor tracking. The low-profile shape is designed to reduce arm and wrist movement while using less desk space than a conventional mouse. A rechargeable battery provides up to four months of operation between charges, and the included USB-C cable also supports connected use. For organizations with mixed USB hardware, the package includes a USB-A dongle with a USB-C-to-USB-A adapter.
Programmability is the standout feature. KensingtonKonnect can assign a broad selection of functions to eight sets of programmable buttons, making it easier to build task-specific profiles for demanding workflows. That sophistication has trade-offs: users who only need basic pointing and clicking may find the setup more involved than necessary. The stated software limitation for Windows ARM-based computers also deserves attention, and the Pro does not use the physical scroll ring associated with the Expert model.
Choose the SlimBlade Pro when you value a rechargeable battery, multiple connection paths, and deep button customization enough to accept a more advanced configuration process. It is a premium fit for analysts, developers, designers, and heavy multitaskers who want one adaptable pointing device across several systems.
Rechargeable Multi-Mode Connectivity
The ability to switch among Bluetooth, 2.4GHz, and wired operation provides useful flexibility for different computers and workspaces. The rechargeable design removes routine battery replacement, while four months of stated battery life simplifies long-term maintenance.
Deep Workflow Personalization
Eight sets of programmable buttons can store different configurations for work and personal activities. This is more capable than the basic customization found on several Orbit models and is particularly useful for frequent shortcut and macro users.

3. Kensington Orbit Trackball Mouse with Scroll Ring – Best Scrolling Kensington Trackball
Kensington Orbit Trackball Mouse with Scroll Ring
40mm optical tracking ball
Wired USB connectivity
Dedicated mechanical scroll ring
Detachable wrist support
The Kensington Orbit Trackball Mouse with Scroll Ring earned a 4.3 rating and stands out for its tactile, dedicated scroll ring. The 40mm ball uses optical tracking and a specially designed hard spherical surface, offering precise control in a familiar index-finger trackball format.
Pros
- Excellent dedicated scroll ring
- Precise spherical ball
- Soft detachable wrist rest
- Ambidextrous operation
- Basic button customization
Cons
- Wired-only connection
- Only two customizable buttons

The scroll ring is the defining feature. Instead of rolling a separate wheel, users spin the ring to move through web pages, spreadsheets, and documents. Its physical feedback and generous scrolling range make it especially appealing for people who spend considerable time navigating long content. The compact ambidextrous body works for either hand, and the detachable wrist rest softly supports extended sessions.
Two programmable buttons, adjustable cursor speed, and adjustable scrolling speed are available through KensingtonKonnect. That is sufficient for basic productivity shortcuts, though it is less flexible than the Expert and SlimBlade Pro. The product is also wired, which avoids charging, pairing, and wireless interference but limits portability. ChromeOS users can operate basic HID functions but cannot customize the device through the software.
This Orbit is a strong choice for users who specifically want a scroll ring without moving to a wireless model. It suits document-heavy office work, web research, spreadsheet navigation, and anyone who prefers the mechanical feedback of turning a ring. It is also a more focused option than the broader Expert wireless model.
A More Tactile Way to Scroll
The raised scroll ring provides a distinct physical action for moving through pages and documents. It can be easier to locate than a small wheel and offers clear tactile feedback during long navigation sessions.
Classic Orbit Ergonomics
The detachable wrist rest and ambidextrous shape make the 40mm ball approachable for either hand. A wired USB connection keeps setup simple, while the optical sphere supports controlled cursor movement.

4. Kensington Orbit Trackball Mouse – Best Budget Kensington Trackball
Kensington Orbit Trackball Mouse
40mm red optical trackball
Wired USB connectivity
Two programmable buttons
Compact ambidextrous design
The Kensington Orbit Trackball Mouse is a straightforward, economical entry point into the trackball category. Its 4.2 rating reflects reliable basic operation, a compact ambidextrous body, and a straightforward wired USB connection that requires no batteries.
Pros
- Simple USB installation
- No battery required
- Compact desktop footprint
- Basic customization support
- Works with major platforms
Cons
- No dedicated scroll ring
- Limited two-button customization
We may earn a commission when you buy through this link, at no additional cost to you.
Internal red optics track the movements of the medium 40mm ball, providing the kind of precise cursor placement many users expect from a trackball. The device takes up substantially less desk space than a mouse requires for movement, which is useful on compact work surfaces. KensingtonKonnect adds cursor-speed adjustment and program-function assignment for each of the two buttons.
The main compromise is the absence of a scroll ring. Users must use their regular click buttons for page navigation, which may feel less fluid than the dedicated ring offered by another Orbit model. The two-button feature set is also modest compared with the Expert, SlimBlade Pro, and TB675. Nevertheless, these limitations are understandable for a model focused on core functionality and uncomplicated ownership.
This is the best budget pick for buyers who want to try an ergonomic pointing device without dealing with wireless pairing, charging, or batteries. It is appropriate for students, office workers, and anyone with a small desk who values a compact footprint and straightforward USB installation over advanced scrolling and multi-device features.
Low-Maintenance Wired Operation
A reliable USB connection means there is no battery to charge or replace and no receiver to pair. For a fixed workstation, this can be the simplest and most consistent way to operate a trackball.
Compact Entry-Level Control
The 40mm optical ball provides accurate cursor movement in a small housing. Basic button and speed customization covers routine productivity needs without introducing the complexity of a highly programmable multi-device model.

5. Kensington Wired SlimBlade Trackball Mouse – Best Low-Profile Wired Kensington Trackball
Kensington Wired SlimBlade Trackball Mouse
SlimBlade laser tracking
Wired USB connectivity
Low-profile ambidextrous design
KensingtonWorks button customization
The Kensington Wired SlimBlade Trackball Mouse offers a low-profile alternative to the rounder Orbit design. It carries a 4.3 rating and emphasizes a reduced desk footprint, less arm and wrist movement, and precise laser-based cursor control.
Pros
- Slim desktop profile
- Smooth laser tracking
- Less arm and wrist movement
- Works with either hand
- Simple wired setup
Cons
- No advanced connectivity options
- Limited customization details
We may earn a commission when you buy through this link, at no additional cost to you.
Its shape is thin and understated, with a silver metallic finish that gives the device a more streamlined appearance. The ambidextrous design makes it possible to use the ball with either hand, while the wired connection removes the need for batteries and wireless pairing. KensingtonWorks software supports button customization for users who want to adapt the primary controls.
Compared with the larger Orbit and Expert models, the SlimBlade's low profile is its defining characteristic. It can feel visually and physically less substantial, which may suit users who prefer a subtle desk setup. The supplied information does not highlight a separate scroll ring or four-level DPI selector, so buyers should not assume those conveniences are included.
This model is best for wired workstations where space and visual neatness matter. It suits people who want a traditional index-finger trackball without a large wrist rest or tall housing. Those needing a physical scroll wheel, extensive programmability, or multi-device wireless operation should examine the Expert and SlimBlade Pro instead.
Slim Design for Limited Desks
The low-profile housing occupies less space than a mouse and leaves room for keyboards, notes, and other essentials. Its shape is especially attractive for users creating a clean, minimalist workstation.
Precise and Familiar Operation
Laser tracking delivers controlled cursor movement, while the ambidextrous body supports either hand. The wired connection provides dependable everyday operation and avoids the charging and receiver-management demands of wireless models.

6. Kensington Orbit Wireless Trackball with Scroll Ring – Best Wireless Scroll-Ring Trackball
Kensington Orbit Wireless Trackball with Scroll Ring
40mm optical tracking ball
2.4GHz and Bluetooth connectivity
Four selectable DPI levels
Detachable ergonomic wrist rest
The Kensington Orbit Wireless Trackball with Scroll Ring is a particularly complete wireless option, combining the Orbit family's familiar 40mm ball and mechanical scroll ring with both 2.4GHz and Bluetooth connectivity. Its 4.2 rating reflects a versatile feature set for mobile work.
Pros
- Excellent combined scrolling and wireless
- Encrypted 2.4GHz connection
- Four practical DPI levels
- Customizable buttons and speeds
- Detachable wrist support
Cons
- Requires wireless setup
- Bluetooth version may be limiting
We may earn a commission when you buy through this link, at no additional cost to you.
The 2.4GHz receiver connection includes 128-bit AES government-grade encryption, while Bluetooth support adds convenient pairing with compatible devices. Four DPI settings—400, 800, 1,200, and 1,600—allow users to move between precise editing and faster navigation. KensingtonKonnect expands the experience with programmable buttons and cursor and scroll-speed adjustments.
A detachable wrist rest supports longer use, and the ambidextrous shape works for either hand. Compared with the wired Orbit with Scroll Ring, this model adds mobility and adjustable precision. Its trade-offs are the need to manage a receiver or Bluetooth pairing and the absence of a rechargeable battery, meaning ongoing battery availability should be considered.
This is a strong match for users who want a mechanical scroll ring and wireless freedom but do not need the more extensive programmability of the SlimBlade Pro. It works well for travel, shared spaces, and hybrid workflows where moving between computers is common.
Useful Cursor-Speed Range
Four DPI levels provide more control than a single fixed speed. Fine settings help with text editing and precise cursor placement, while higher levels suit word processing, casual browsing, and rapid movement across large displays.
Secure Wireless and Easy Scrolling
The 2.4GHz option includes 128-bit AES encryption, while Bluetooth offers a receiver-free alternative. Combined with the dedicated scroll ring, the model delivers a practical mix of secure connectivity, mobility, and navigation.

7. Kensington Orbit Wireless Trackball with Touch Scroll Ring – Best Compact Wireless Kensington Trackball
Kensington Orbit Wireless Trackball with Touch Scroll Ring
32mm compact trackball
Bluetooth LE and USB receiver
Touch-operated scroll ring
Small-to-average hand support
The Kensington Orbit Wireless Trackball Mouse with Touch Scroll Ring is built around a compact 32mm ball and a distinctly small housing. Its 4.2 rating reflects a convenient design for users with small to average-sized hands who want a trackball that occupies minimal desk space.
Pros
- Exceptionally compact footprint
- Wireless connection options
- Touch scrolling with clear movement
- No driver installation required
- Works with either hand
Cons
- Small ball limits surface area
- Designed for smaller hands
We may earn a commission when you buy through this link, at no additional cost to you.
Wireless connectivity is available through Bluetooth LE or a USB nano receiver, allowing users to choose between direct pairing and a dedicated receiver. The touch scroll ring permits movement through web pages and documents, while plug-and-play operation means no driver installation is required. KensingtonKonnect provides customization for a more personalized workflow.
The main consideration is size. A 32mm ball requires users to roll the ball with more finger movement than they would with the 40mm or 55mm balls found elsewhere in this list. It is also explicitly designed to fit smaller hands, so users with larger hands may find the shape less comfortable. The touch ring is convenient, although it lacks the same mechanical rotational feel as a physical scroll ring.
Choose this model for a small travel kit, compact office, or shared workstation where every centimeter matters. It is a sensible choice for smaller hands and users who value easy wireless setup and touch navigation more than the broad, smooth surface of a large trackball.
Compactness for Smaller Hands
The 32mm ball and compact body create a trackball intended for small to average-sized hands. This focused design can feel especially appropriate in confined spaces where a larger model would take up too much room.
Receiver-Free or Receiver-Based Wireless
Bluetooth LE supports a direct wireless connection, while the USB nano receiver offers an alternative setup. Plug-and-play operation keeps installation uncomplicated, and KensingtonKonnect adds further personalization.

8. Kensington Orbit Optical Trackball Mouse – Best Simple Wired Orbit Trackball
Kensington Orbit Optical Trackball Mouse
40mm optical tracking ball
Wired USB 2.0 connection
Plug-and-play USB setup
Compact ambidextrous body
The Kensington Orbit Optical Trackball Mouse is a basic wired model with a 4.0 rating. Its central strengths are the familiar 40mm optical ball, a compact footprint, and a plug-and-play USB 2.0 connection that makes it easy to add to an existing computer setup.
Pros
- Simple plug-and-play operation
- Accurate optical tracking
- Perfectly spherical ball surface
- Compact desk footprint
- Ambidextrous design
Cons
- Minimal feature specification
- No stated scroll ring
We may earn a commission when you buy through this link, at no additional cost to you.
The medium ball is shaped as a precise sphere and is monitored by optical tracking technology for accurate cursor control. The ambidextrous shell works equally well for left- and right-handed users, and its small base requires less movement space than a conventional mouse. The wired connection also eliminates batteries, charging, and wireless pairing.
Compared with the other Orbit models, this listing provides a more minimal feature description. It does not highlight a scroll ring, software-based customization, or advanced DPI controls. That simplicity may be an advantage for buyers who want a straightforward pointing device, but it also means the model offers fewer options for scrolling and workflow adaptation.
This trackball is best for a fixed desk, shared office, or learner who wants uncomplicated USB operation and accurate optical control. It is a sensible alternative to the silver-and-black budget Orbit when the appearance of that model better matches your setup. Users who want a ring or wireless freedom should consider the more specialized Orbit variants.
Reliable Optical Precision
Optical tracking and a perfectly spherical 40mm ball provide a controlled surface for cursor placement. The design supports accurate movement without requiring a separate mouse pad or repeated hand repositioning.
Minimal Setup Requirements
Plug-and-play USB 2.0 operation keeps installation simple. With no battery or wireless pairing required, the mouse is particularly practical for fixed workstations and shared technical environments.

9. Kensington TB675 Wireless Vertical Trackball – Best Multi-Device Vertical Kensington Trackball
Kensington TB675 Wireless Vertical Trackball
34mm thumb-operated trackball
60-degree vertical ergonomic angle
Four-device wireless switching
Nine programmable buttons
The Kensington TB675 Wireless Vertical Trackball is the most specialized model in the guide. With a 3.8 rating, it distinguishes itself through a 60-degree vertical design, thumb-operated 34mm ball, rechargeable construction, and the ability to connect to four devices at once.
Pros
- Natural 60-degree wrist angle
- Switches among four devices
- Rechargeable USB-C design
- Metal four-direction scroll wheel
- Extensive button customization
Cons
- Lower rating than other picks
- Vertical format takes adjustment
We may earn a commission when you buy through this link, at no additional cost to you.
The vertical form is designed to support more natural wrist and thumb positioning, and the product is described as well suited to average-sized hands. Its four-direction metal scroll wheel supports vertical scrolling plus side-to-side movement, which can be valuable in wide spreadsheets, timelines, and large documents. Four DPI settings range from 400 to 1,600 for different levels of precision.
Connectivity is unusually flexible. A 2.4GHz dongle, dual Bluetooth, and wired USB-C operation are all available, with a built-in device selector for switching among up to four devices. The 2.4GHz connection uses 128-bit AES encryption. Nine programmable buttons can be customized through Kensington Konnect, including the two assignable side buttons, with shortcuts and macros available for deeper workflows.
The main caution is that a vertical trackball is a different ergonomic proposition from the index-finger models in this list. Users accustomed to conventional mouse movement may need time to adapt to thumb operation. Its rating is also lower than the other featured products, so hands-on comfort and workflow fit are especially important considerations. Despite that, it is the clearest choice for someone who prioritizes vertical wrist positioning, rechargeable power, and effortless multi-device switching.
Vertical Ergonomics for Thumb Control
The 60-degree vertical angle positions the wrist and thumb more naturally than a flat mouse. The 34mm ball is operated by the thumb, so this model is most appropriate for users who prefer that movement pattern and average-sized hands.
Four-Device Workflow Support
Dual Bluetooth, a 2.4GHz receiver, and wired USB-C provide several ways to connect. A built-in selector makes it practical to move among several systems, while nine customizable buttons and the metal four-direction wheel support complex office tasks.

10. Kensington Slimblade Trackball – Best Compact Traditional Kensington Trackball
Kensington Slimblade Trackball
SlimBlade trackball mechanism
Low-profile ergonomic shape
Compact desktop footprint
Traditional index-finger control
The Kensington Slimblade Trackball has the highest customer rating in this roundup at 4.5. Its name corresponds to the Kensington Slimblade Trackball K72327US, placing it within the same low-profile product family as the wired SlimBlade model reviewed earlier.
Pros
- Highest rating in the guide
- Slim space-saving design
- Traditional trackball operation
- Simple ergonomic footprint
- Well-regarded cursor control
Cons
- Limited supplied specification
- Fewer documented feature details
We may earn a commission when you buy through this link, at no additional cost to you.
The central appeal is a slim trackball format that minimizes the desk space required for cursor operation. It preserves the familiar index-finger technique associated with conventional trackballs while avoiding the taller shape of many ergonomic models. That makes it a practical choice for users who want a modest footprint without moving to a thumb-operated vertical design.
The available product data is notably brief, so it would be inappropriate to assume features that are not stated. Buyers should examine the current listing for exact connectivity, button configuration, ball size, included accessories, and software details. The paired wired SlimBlade model offers useful context: it is ambidextrous, uses laser tracking, has a low-profile form, and supports button customization through KensingtonWorks.
With the highest rating and a proven slim format, this trackball is an attractive option for users who values a traditional trackball experience, compact design, and positive customer feedback. It is especially relevant to fixed workspaces where a low-profile pointing device provides visual and physical space savings. Confirm the current specification and platform support before ordering.
Compact Traditional Trackball Design
The slim form preserves familiar index-finger trackball operation while reducing the amount of space occupied on the desk. It suits users who do not want the larger housing of an Orbit model or the steep angle of a vertical trackball.
Strong Customer Feedback
A 4.5 rating is the highest among the ten products included. That makes the Slimblade a strong candidate for buyers who place a high value on customer satisfaction, although the current product page should still be checked for complete technical details.

Buying Guide – How to Choose the Best Kensington Trackball
The right Kensington trackball depends less on brand than on fit: consider ball size, control style, scrolling habits, connection method, available desk space, and the amount of customization your work requires.
Choose the Right Ball Size
Ball size directly affects control, finger movement, and the surface area available for precise positioning. The featured products range from a compact 32mm ball to large 55mm models. A 32mm ball takes up less space and suits small to average hands, while 40mm models provide a middle-ground experience. The 55mm Expert and SlimBlade Pro balls offer a broad surface that can make rolling and fine corrections feel easier, particularly for index-finger users. Consider both hand size and the amount of desk space available before selecting a diameter.
Pick Your Preferred Control Style
Most Kensington trackballs use an index-finger-controlled ball, closely resembling the motion of a standard mouse without requiring a mouse pad. The TB675 is different: its 34mm ball is controlled with the thumb on a 60-degree vertical body. That format may support a more natural wrist position for users who adapt well to it, but it requires a different muscle-memory pattern. Existing comfort with a conventional mouse is an important reason to remain with an index-finger design, while thumb operation may suit users who prefer a vertical silhouette.
Decide Between Wired and Wireless
A wired trackball provides a dependable connection without batteries, charging, pairing, or receiver management. It is a strong choice for a permanent desk where a cable is acceptable. Wireless models offer mobility and cleaner workspaces, but they add considerations such as battery life, receiver storage, Bluetooth pairing, and connection switching. The Expert supports Bluetooth LE and 2.4GHz, while the Orbit Wireless Scroll Ring supports 2.4GHz and Bluetooth. The SlimBlade Pro and TB675 go further by also offering wired operation alongside wireless modes.
Evaluate the Scrolling Mechanism
Scrolling behavior is one of the biggest differences among these trackballs. A physical scroll ring, as found on the Expert, wired Orbit Scroll Ring, and wireless Orbit Scroll Ring, provides a distinct rotational action for moving through documents. The smaller Orbit Touch Scroll Ring uses touch rather than a raised mechanical ring. Other models rely on the standard primary click controls for scrolling. If you navigate long documents, work with spreadsheets, or browse the web extensively, compare the ring models carefully rather than assuming all trackballs scroll in the same way.
Assess Button Customization
The number of programmable buttons determines how well a trackball can support shortcuts, macros, and application-specific workflows. Basic Orbit models provide two customizable buttons, the Expert adds four, and the SlimBlade Pro supports eight sets of programmable buttons. The TB675 goes furthest with nine buttons, including assignable side controls. KensingtonKonnect and KensingtonWorks are central to these features, so also confirm that the desired computer platform is supported. Windows ARM-based systems are currently not supported by the software for the Expert and SlimBlade Pro.
Match the Model to Your Workstation
A compact workstation may benefit from the small footprint of the 32mm Orbit or low-profile SlimBlade design. The Expert's larger ball and detachable wrist rest suit users who want a fuller support experience. The TB675 occupies more vertical space because of its 60-degree angle, but it offers a different wrist orientation. Consider wrist rests, hand size, monitor distance, available arm movement, and the amount of open desk space. An ergonomic product only helps when its shape and controls fit your normal working position.
Check Device and Software Compatibility
Most of the products list support for Windows, macOS, and ChromeOS, but exact operating-system versions and customization limits vary. Wired models generally provide the most straightforward installation. Wireless options require compatible Bluetooth or a supplied receiver. The wired Orbit Scroll Ring provides basic ChromeOS HID functions but cannot be customized through KensingtonWorks, and the Expert and SlimBlade Pro currently exclude Windows ARM systems from customization. Check the current listing before ordering if you use an unusual platform or rely on specific application functions.
How to Use and Care for Your Kensington Trackball
Begin by placing the trackball directly in front of your keyboard rather than to one side. For an index-finger model, support the hand lightly and rest the index finger on top of the ball. For the TB675, position the thumb naturally over its smaller ball and allow the wrist to remain relaxed rather than sharply bent. Keep the device close enough that you can reach all buttons without lifting your arm or twisting your wrist.
Move the ball with slow, controlled finger movements. Large, rapid spins are effective for crossing the screen, but fine placement and menu selection generally work better with shorter rolls. Use the scroll ring for long documents when your model includes one, and use the four-direction wheel for horizontal navigation where supported. After installing KensingtonKonnect or KensingtonWorks, configure cursor speed, scroll behavior, and buttons for the applications you use most often.
For care, disconnect the device before cleaning it and avoid pushing excessive force into the ball. Use a soft, dry or lightly dampened cloth to wipe the exterior and the exposed ball area, and keep liquids away from openings, buttons, and charging contacts. Store wireless models with adequate battery charge if they will sit unused for a long period. Do not attempt to open the housing, and consult the current manufacturer guidance for troubleshooting, firmware or software updates, replacement accessories, and warranty coverage.
Frequently Asked Questions
Are Kensington trackballs suitable for both left-handed and right-handed users?
Most of the featured models have an ambidextrous design intended to work equally well for either hand. The Expert, Orbit family, and wired SlimBlade explicitly support left- and right-handed use. The TB675 is different because its vertical design and thumb-operated ball are shaped around a particular hand position, so prospective buyers should consider their grip and hand size carefully.
Is a trackball more accurate than a standard computer mouse?
A trackball can provide excellent precision because the ball stays in a fixed position while the user rotates it with the fingers. It also requires less desk space and less whole-arm movement than a mouse. Accuracy still depends on ball condition, tracking quality, user technique, pointer-speed settings, and the quality of the optical or laser sensor.
What is the difference between a scroll ring and a standard mouse wheel?
A scroll ring is a raised circular control that is rotated like a dial to move through pages or documents. A standard mouse wheel is rolled up and down between the primary buttons. The Expert and two featured Orbit models use a scroll ring, while the compact wireless Orbit uses a touch-style ring. The remaining products do not highlight a dedicated ring in the supplied specifications.
Do I need KensingtonKonnect to use a Kensington trackball?
Basic pointing, clicking, and scrolling generally work without the software. KensingtonKonnect or KensingtonWorks is needed to assign custom button functions and adjust certain cursor or scrolling speeds. Compatibility varies by model and operating system, so check the product listing before relying on advanced customization, particularly on ChromeOS or Windows ARM-based systems.
Can I use one Kensington trackball with multiple computers?
That depends on the model. The TB675 can connect to up to four devices through its 2.4GHz receiver, dual Bluetooth, and wired USB-C options, and it includes a device selector. The Expert and SlimBlade Pro also support multiple connection modes, which can make switching practical. The basic Orbit and wired SlimBlade models are designed around a single wired connection.
How do I clean a trackball without damaging it?
Disconnect the mouse first, then wipe the housing and exposed ball with a soft, dry or lightly dampened cloth. Keep moisture from entering button gaps, ports, and other openings, and do not push sharply on the ball or open the housing. For stubborn debris, follow the current manufacturer instructions so that cleaning does not affect the trackball mechanism or its warranty.
Should I choose a large-ball or small-ball trackball?
A large 55mm ball provides a broad operating surface and can feel smooth for index-finger users, while 40mm models offer a middle ground. A 32mm ball is more compact and is explicitly intended for small to average-sized hands. The best choice depends on hand size, desk space, and whether you prefer a larger surface or a smaller footprint.
Are rechargeable Kensington trackballs more convenient than battery-powered models?
A rechargeable model removes the need to replace disposable batteries and can be especially convenient for frequent users. The SlimBlade Pro provides a rechargeable battery with a stated four-month life and USB-C charging. Some wireless Orbit models use replaceable batteries, so compare charging routines, battery availability, and the convenience of your preferred connection method before purchasing.
Final Thoughts on Choosing the Best Kensington Trackball
The Kensington Expert Wireless Trackball is the best all-around recommendation because it balances a large 55mm ball, wireless flexibility, customization, a detachable wrist rest, and broad platform support. The SlimBlade Pro stands out as the premium option for rechargeable power, three connection methods, and extensive button profiles, while the basic Orbit Trackball Mouse is the best budget choice for a compact, battery-free wired setup.
Prioritize the factors that change daily use: choose a physical scroll ring for frequent document navigation, a large ball for broad index-finger control, a compact model for a small desk, or the vertical TB675 for thumb control and four-device switching. Check the supplied operating-system requirements carefully if you depend on KensingtonKonnect, and consider whether a wired device's simplicity is preferable to wireless mobility.
Product details and pricing can change, so review the current listing, included accessories, software compatibility, warranty information, and available color or model variations before making a final purchase. The most suitable Kensington trackball is the one that fits your hand, desk, devices, and daily workflow rather than simply having the longest feature list.
