Trackball mice have earned a small but consistent following among people who depend on precise, stationary pointing every day: programmers, editors, CAD users, and anyone tired of chasing a cursor across the desk. If your current setup has you thinking about wrist and forearm comfort, swapping a moving mouse for a stationary ball is one of the most direct changes you can make to how you point.
The category splits early and decisively into two families. Thumb-operated trackballs, led by Logitech's current MX Ergo line, feel closest to a conventional mouse and are the easiest transition for most people. Finger-operated models — central balls controlled with the index and middle fingers — are often ambidextrous and carry a completely different scroll and button layout. Neither style is objectively better; the right choice depends on which hand you use, how you like to scroll, and how many controls you want within reach.
This guide ranks eight current trackball mice across the thumb/finger split, with attention to what matters in daily use: handedness, hand size, scroll method, button count, connectivity, polling rate, and maintenance. The picks span budget through premium, and each one is tied to a specific use case rather than a single best-for-everyone score.
The models below fit anyone moving away from a conventional mouse, left-handed or alternating-hand users who need a genuinely ambidextrous shell, power users on high-refresh displays, and workstation users who want to reclaim desk space without giving up fine cursor control.

What Makes a Great Trackball Mouse?
A trackball is defined by a handful of decisions that matter far more than headline sensor specs. These are the criteria used to rank the picks below.
Thumb-operated vs. finger-operated
This is the fundamental split of the category. Thumb-operated designs put the ball under the thumb of a right-handed shell and retain a conventional left/right button layout, which makes them the easiest transition from a normal mouse. Finger-operated designs center a larger ball under the index and middle fingers, which enables ambidextrous shells and frees the thumb for other inputs. The two control styles are different enough that personal preference usually outweighs any spec difference.
Handedness and hand size
Only a few trackballs are genuinely ambidextrous: the Kensington SlimBlade Pro, Expert Wireless, and Orbit Wireless. The MX Ergo S, M575S, HUGE Plus, DEFT PRO, and EX-G PRO are all shaped around right-handed operation, which matters immediately for left-handed buyers. Hand size narrows the field further — the HUGE Plus is explicitly a large-body design, while the DEFT PRO trades footprint for a smaller, denser shell. If a trackball doesn't fit, a conventional ergonomic mouse may still be the better answer.
Scroll method matters more than you'd expect
Trackballs replace the wheel with three competing approaches. The SlimBlade Pro uses twist-to-scroll: you rotate the ball itself around its vertical axis. Kensington's Expert and Orbit use a dedicated scroll ring around the ball. ELECOM's models and the M575S use tilt wheels or conventional wheel inputs. The twist mechanism is polarizing — some long-time users refuse to part with it, while others never adapt — so scroll preference should be settled before you buy.
Buttons, software, and onboard memory
Button count is not the same as usable customization. Logitech relies on Options+, Kensington on Konnect, and ELECOM on Mouse Assistant, and the depth of per-application mapping varies across all three. One current caveat: ELECOM still lists onboard memory for the HUGE Plus as a future firmware feature, which means stored profiles aren't yet available on that model despite its high button count.
Connectivity and polling rate
Most trackballs pair over a 2.4 GHz receiver and Bluetooth, with ELECOM adding wired USB on several tri-mode models. Polling rate is where the category splits: traditional office trackballs such as the SlimBlade Pro run around 125 Hz, which is fine for documents but can show cursor stepping on high-refresh displays. The HUGE Plus advertises 1,000 Hz, making it the rare productivity trackball built for smooth motion on a 120 Hz or faster monitor. For the broader connectivity picture, the wireless mouse buying guide covers dongle-vs-Bluetooth trade-offs in detail.
Bearings, ball size, and maintenance
Ball size changes the feel of precise movement: the 55 mm Expert ball and 52 mm HUGE Plus ball favor large, deliberate sweeps, while the 34 mm EX-G PRO ball suits smaller thumb adjustments. Static-bearing designs — most of the category — require occasional cleaning and can exhibit slight stiction during tiny movements. ELECOM addresses this directly with user-swappable steel bearings on the HUGE Plus, and several of its models accept synthetic ruby replacements. Regular ball and cavity cleaning is normal upkeep, not a defect signal.
#1 Logitech MX Ergo S — Best Overall Thumb Trackball
The MX Ergo S is the current successor to Logitech's long-running MX ERGO and the easiest high-end recommendation for a right-handed user moving from a conventional mouse. The shape is a soft-rubber sculpted body with an adjustable tilt plate that moves between a flat position and a 20-degree angle, letting the hand settle wherever it feels most natural. Logitech sizes the shell for medium-to-large hands.
One note on model history: some third-party benchmark data still refers to the earlier MX ERGO chassis rather than the S revision. The S-specific updates are USB-C charging, Logi Bolt connectivity, and quieter primary clicks, while the core tilt-and-ball platform carries over from the well-known predecessor.
Key specs:
- Right-handed, thumb-operated, 20-degree adjustable tilt
- Soft-rubber sculpted body intended for medium-to-large hands
- Six customizable buttons plus DPI switching via Logi Options+
- Quiet primary clicks
- Rechargeable battery with USB-C; up to 120 days claimed per charge and roughly 24 hours from a one-minute quick charge
- Logi Bolt receiver and Bluetooth Low Energy with multi-device support
Pros:
- Adjustable tilt lets the hand settle at a comfortable angle
- USB-C charging with a long rated battery life
- Quiet clicks and six customizable buttons
Cons:
- Still lacks a free-spinning wheel despite the premium tier
- Right-handed only
Verdict: The strongest overall pick for right-handed productivity users who want a thumb ball without giving up tilt, modern charging, or multi-device control.
Perfect for: Office and productivity users with medium-to-large hands upgrading from a standard mouse.
#2 Kensington SlimBlade Pro — Best Finger-Operated, Ambidextrous Pick
The SlimBlade Pro is the strongest current option for left-handed users or anyone who alternates hands at a workstation. The central finger-operated ball sits in a low-profile, truly ambidextrous shell, and the signature scroll mechanic is twist-to-scroll: rotating the ball itself replaces the wheel entirely.
Connectivity is 2.4 GHz and Bluetooth on the current US SKU, with AES-encrypted wireless and a nano receiver. Additional regional variants list wired operation as well, so the exact connection set should be confirmed against the specific unit before purchase. RTINGS measured the SlimBlade Pro's maximum polling around 125 Hz, which places it firmly in office/productivity territory rather than gaming.
Key specs:
- Finger-operated central ball in a genuinely ambidextrous shell
- Twist-to-scroll instead of a conventional wheel
- Rechargeable internal battery
- 2.4 GHz USB receiver and Bluetooth wireless; AES-encrypted
- Four large programmable button zones
- Kensington Konnect software for Windows and macOS
- Maximum polling around 125 Hz, measured by RTINGS
- Three-year limited warranty
Pros:
- Genuinely ambidextrous — a rare fit for left-handed use
- Twist-to-scroll frees the thumb from wheel duty
- Rechargeable with encrypted wireless
Cons:
- Twist-to-scroll has a real learning curve
- Office-class polling limits appeal for gaming
Verdict: The best finger-operated, ambidextrous trackball for users who prioritize left-handed or alternating-hand control and can adapt to twist scrolling.
Perfect for: Left-handed or alternating-hand users on multi-device desks.
#3 Logitech ERGO M575S — Best Value Thumb Trackball
The M575S is the low-risk entry point for anyone who specifically wants a thumb ball. It strips away the MX Ergo S's tilt plate, rechargeable battery, and extra workflow controls in favor of a simpler, lighter package at a budget tier. The shape is a compact right-handed wedge with a sculpted palm area and a thumb ball under the primary buttons.
Despite the lower price, the core hardware is current: Logitech Advanced Optical Tracking, Bluetooth LE plus a Logi Bolt receiver, and quieter primary clicks than the previous M575. A single AA battery drives up to 18 months of claimed life, which is among the longest in the category.
Key specs:
- Right-handed, thumb-operated
- 134 × 100 × 48 mm, 145 g
- Advanced Optical Tracking; 400 DPI nominal, up to 2,000 DPI
- Five buttons total (left/right, back, forward, clickable wheel); three customizable
- Bluetooth Low Energy and Logi Bolt receiver
- Up to 10 m wireless range

#4 ELECOM HUGE Plus — Best Power-User Finger Trackball
The HUGE Plus is the most technically ambitious productivity trackball in the current lineup. It answers several long-standing enthusiast complaints about the original HUGE with a 1,000 Hz polling rate, modern tri-mode connectivity, user-swappable bearings, and a rechargeable battery.
The design is deliberately large: a 52 mm finger ball, ten programmable buttons including tilt-scroll inputs, and a low-resilience cushioned palm support. The high polling rate makes it the standout choice for high-refresh displays, where the office-class 125 Hz rate of most trackballs begins to show stepping.
Key specs:
- Right-handed, finger-operated, large-body design (4.5 × 7.2 × 2.3 in, 10.3 oz)
- 52 mm ball with ten programmable buttons, including tilt-scroll inputs
- USB-C wired, 2.4 GHz, and Bluetooth 5.3; pairs with up to three devices

Perfect for: Power users with large hands who want 1,000 Hz motion and dense controls.
#5 Kensington Expert Mouse Wireless — Best Classic Large-Ball, Scroll-Ring Pick
The Expert Wireless keeps the classic Kensington formula relevant: a large 55 mm finger ball surrounded by a dedicated scroll ring, all in a symmetrical, ambidextrous shell. It is the model to choose if you want the scroll-ring experience without the SlimBlade's twist-to-scroll mechanic.
The four-button layout is deliberately simple, and the package includes a detachable wrist rest. Connectivity spans 2.4 GHz and Bluetooth LE with AES encryption and a nano receiver stored inside the device. A single AA battery provides power, with auto wake/sleep for efficiency.
Key specs:

Perfect for: Scroll-ring fans and users with large, multi-monitor workstations.
#6 ELECOM DEFT PRO — Best Compact Finger-Operated Trackball
The DEFT PRO fills the gap between Kensington's two-button Orbit and the oversized HUGE Plus: a right-hand-oriented finger trackball with eight physical buttons, horizontal tilt scrolling, and tri-mode connectivity in a compact body built around a 44 mm ball.
The button count and layout give it substantially more control density than the Orbit's two-button design, while the smaller footprint makes it a frequent alternative for users who found the HUGE family too wide. A single AA battery drives the wireless modes, with estimated runtimes stretching from roughly 211 to 366 days depending on connection.
Key specs:
- Right-hand-oriented, finger-operated with a 44 mm ball
- Tri-mode: wired USB, 2.4 GHz receiver, Bluetooth 4.0

Perfect for: Users seeking a smaller finger ball with more controls than a two-button Orbit.
#7 ELECOM EX-G PRO — Best Button-Rich Thumb Alternative
The EX-G PRO is the enthusiast-oriented answer for buyers who want the thumb-ball layout of a Logitech but with ELECOM's denser control set. It combines a 34 mm thumb ball with eight buttons, horizontal tilt scrolling, and the same tri-mode connectivity found across ELECOM's current trackball line.
Ranked below the MX Ergo S and M575S for general buyers because the fit is more specific: it rewards users who want wired, 2.4 GHz, and Bluetooth in one unit, or who prefer a smaller thumb ball with more inputs. The recurring enthusiast complaint is static friction on tiny, precise movements, which some owners address with aftermarket bearing swaps — an optional modification, not a required fix.
Key specs:
- Right-handed, thumb-operated with a 34 mm ball
- Tri-mode: wired USB, 2.4 GHz, Bluetooth 4.0
- Gaming-grade optical sensor; 500 / 1,000 / 1,500 DPI
- Eight buttons plus horizontal tilt scrolling
- 2.5 mm synthetic ruby support bearings
- Omron primary switches rated 10 million clicks

- 108 × 135 × 47.7 mm, approximately 147 g
- Receiver storage; three-year warranty
Pros:
- Eight buttons and tri-mode connectivity on a thumb ball
- Wired operation with no battery required
- Long estimated battery life
Cons:
- Stiction on tiny movements is a recurring owner complaint
- A more specific fit than the mainstream Logitech thumb picks
Verdict: A capable, button-rich thumb alternative that makes the most sense for users who want tri-mode flexibility and don't mind a smaller ball.
Perfect for: Enthusiasts seeking thumb-ball layout with dense controls and wired fallback.
#8 Kensington Orbit Wireless — Best Budget Ambidextrous Trackball
The Orbit Wireless is the simplest path into finger-operated trackballs, and the only budget model here that combines an ambidextrous shell with Kensington's scroll ring. It centers a 40 mm ball between two primary buttons and keeps the control set deliberately minimal.
The trade-offs are plain: no shortcut density beyond the two buttons, an office-oriented tracking implementation, and conventional polling. In exchange, buyers get dual wireless connectivity with AES encryption, four DPI presets, a detachable wrist rest, and a three-year warranty at an entry-level tier.
Key specs:
- Finger-operated, center-ball, ambidextrous design
- 40 mm ball with a dedicated scroll ring
- 400 / 800 / 1,200 / 1,600 DPI sensitivity settings
- 2.4 GHz receiver and Bluetooth Low Energy
- 128-bit AES wireless encryption
- Two primary buttons
- Detachable wrist rest
- Three-year limited warranty
Pros:
- Ambidextrous scroll-ring design at an entry-level tier
- Simple, durable layout with a three-year warranty

Polling rate deserves a second look beyond the table: the SlimBlade Pro measures around 125 Hz, while the HUGE Plus advertises 1,000 Hz. On a standard office display the difference is barely perceptible, but on a high-refresh monitor the HUGE Plus is the only model here purpose-built for smooth, fast-motion cursor tracking.
Which Trackball Should You Buy?
Match your use case to one of these profiles rather than chasing the highest spec sheet.
- Moving from a normal mouse, right-handed: Get the MX Ergo S. The familiar left/right button layout and adjustable tilt make it the smoothest transition.
- First trackball on a budget: The M575S covers the essentials with a long battery life and no premium commitment.
- Left-handed or alternating hands: SlimBlade Pro, Expert Wireless, or Orbit Wireless are the genuinely ambidextrous choices; the SlimBlade Pro is the most capable of the three.
- Large hands or high-refresh displays: The HUGE Plus is the only pick with a 1,000 Hz polling rate and a 52 mm ball in a large-body shell.
- Scroll-ring fans: Expert Wireless for a large 55 mm ball, Orbit Wireless for the budget version.
- Compact finger ball with more buttons: DEFT PRO gives eight buttons in a smaller footprint.
- Thumb layout with dense controls: EX-G PRO offers eight buttons and tri-mode connectivity for right-handed users who want more than Logitech's simplest option.
- Still prefer a standard mouse shape? For many desks, a conventional office mouse remains the right tool — the trackball earns its place when stationary pointing or ambidextrous access matters most.
Two models are worth watching but are not ranked here because availability is still settling: the Kensington Expert Mouse Pro TB900 EQ, which adds dual-sensor tracking aimed at fixing the withdrawn TB800's issues, and the recently launched Ploopy A+, which succeeds the Adept with eight buttons and QMK/VIA firmware. Once both are broadly stocked and independently tested, they belong on the shortlist.
Frequently Asked Questions
Q: Are trackball mice actually more ergonomic than regular mice?
A trackball changes the pattern of use rather than curing anything. The device stays in one place on the desk, so pointing motion comes from the thumb or fingers instead of the arm and wrist sweeping across a pad. Some users find that more comfortable or better suited to a limited desk area, but comfort is individual and no pointing device is universally healthier for everyone.
Q: Thumb-operated or finger-operated — which is better?
Neither is objectively better. Thumb balls feel closer to a conventional mouse and are the easiest transition, while finger balls are often ambidextrous and use a different scroll and button layout. The choice usually comes down to personal preference, which is why this guide separates them instead of forcing a single winner.
Q: Do trackballs work for left-handed users?
Only the genuinely ambidextrous models do: the SlimBlade Pro, Expert Wireless, and Orbit Wireless. The MX Ergo S, M575S, HUGE Plus, DEFT PRO, and EX-G PRO are all shaped around right-handed operation.
Q: Can you game with a trackball?
It's possible but limited. Most office trackballs run around 125 Hz polling, which can show cursor stepping on high-refresh displays and feels sluggish in fast aim. The HUGE Plus at 1,000 Hz is the exception, but for competitive play a dedicated gaming mouse still has the edge in latency, weight, and shape selection.
Q: Why does my trackball feel sticky on small movements?
That stiction usually comes from the static bearings under the ball, especially as skin oils and dust accumulate. Clean the ball and support points regularly. On ELECOM models, some owners swap the stock bearings for ceramic or ruby alternatives to smooth out micro-movements, but that is an optional modification rather than a required fix.
Q: How do you clean a trackball?
Pop the ball out through the underside access hole, wipe it with a soft, lint-free cloth, and remove dust from the sensor cavity and support bearings. A dry or very lightly dampened cloth is enough for most models; this is routine maintenance for any trackball, not a sign of a defect.
Q: What's different about the MX Ergo S compared with the older MX ERGO?
The S keeps the adjustable tilt and thumb-ball platform and adds USB-C charging, Logi Bolt connectivity, and quieter main clicks. Some benchmark data still references the earlier chassis, so the current model's specs should be read from Logitech's own documentation rather than assumed identical to older reviews.
Q: Should I wait for the next generation of trackballs?
If you can wait and want the newest hardware, the Kensington Expert Mouse Pro TB900 EQ and the Ploopy A+ are the two to monitor. For a buy-now decision, every model ranked above is currently obtainable, while both of those are still settling into normal retail availability.
Conclusion
The trackball category rewards a clear-eyed decision about control style before anything else. Thumb-operated models convert conventional-mouse habits most easily, while finger-operated models open up ambidextrous layouts and alternative scrolling. Within those two branches, the strongest current picks are the MX Ergo S for mainstream right-handed use and the SlimBlade Pro for left-handed or alternating-hand desks.
For most people, the practical shortlist comes down to three: the MX Ergo S if tilt, charging, and premium polish justify the cost; the M575S if a simple, long-lasting thumb ball is enough; and the HUGE Plus if a large finger ball with 1,000 Hz polling fits a high-refresh setup. Pair any of them with the guidance in the ergonomic mouse guide, the wireless connectivity overview, and the best office mouse roundup to place the trackball correctly within a full desk setup.
If a stationary thumb ball is the direction you're leaning, the MX Ergo S is the cleanest overall recommendation in the current lineup.
