The Best Trackball Mice, From First Try to Full Convert

Key points

• A thumb trackball like the Logitech MX Ergo S keeps your hand in a mouse-like position but shifts cursor control to your thumb alone, which takes one to three weeks of deliberate practice to stop overshooting.
• A finger trackball like the Kensington Expert or ELECOM Huge sits stationary on the desk and uses your index and middle fingers to move a larger ball, requiring no wrist deviation at all once you learn it.
• Trackballs eliminate the forward-and-back arm sweep of a mouse, which matters if your keyboard sits centred or you work from a small desk where mouse travel hits the edge.
• Precision work—pixel-level vector adjustments, CAD, detailed image editing—is harder on a trackball than a mouse for most people, though some long-term users report no difference after six months of daily use.
• Static bearings collect skin oil and dust, making the ball skip after a month or two; cleaning means lifting the ball out and wiping the contact points with isopropyl alcohol on a cloth.
• The Logitech Ergo M575S costs half what the MX Ergo S does and lacks tilt angle adjustment, making it the better starter choice if you are unsure whether you will adapt.

Why trackballs persist: the desk-space and shoulder argument

A trackball does not move. You roll the ball with your thumb or fingers, but the device itself stays where you placed it. That eliminates the forward-and-back sweep a mouse requires, which matters in two situations: you are working from a small desk where the mouse runs out of travel, or you are centring your keyboard and the mouse now sits far enough to the side that reaching it pulls your shoulder forward all day.

The space saving is real but overstated in marketing copy. A trackball needs less lateral desk space than a mouse with room to move, but it still occupies a footprint. The ELECOM Huge is six inches across. You are not suddenly working from a tray table.

The shoulder argument is the stronger one. If you are spending eight hours with your right arm extended to reach a mouse that sits beyond the numeric keypad, you will feel it in your shoulder by about three. A trackball lets you bring the pointing device closer to your body, or lets you centre the keyboard without creating a new problem. Whether that matters depends entirely on your current layout and whether you are already feeling it.

Trackballs do not fix poor posture and they do not eliminate repetitive strain. They shift which muscles do the work.

Thumb balls versus finger balls: two different skills

A thumb trackball looks like a mouse that has been tilted onto its side. Your hand rests on it the way it would rest on a mouse, palm down or slightly rotated, and your thumb controls the ball. The Logitech MX Ergo S and the Logitech Ergo M575S are both thumb trackballs. So is the Nulea M501.

A finger trackball sits flat on the desk, stationary, and you move the ball with your index and middle fingers. The Kensington Expert, the Kensington Orbit, the ELECOM Huge and the ELECOM DEFT PRO are all finger trackballs. Some people call them ambidextrous, which is true but misses the point. The real distinction is that your hand does not grip the device. It rests beside it.

These are not variations on the same input method. They are different motor skills. A thumb trackball requires thumb dexterity and strength you probably do not have yet, because your thumb does not normally make isolated fine movements all day. Most people overshoot for the first week and find small targets harder to hit than they expect.

A finger trackball recruits muscles you already use for typing, but the motion is unfamiliar. You are dragging your fingers across a sphere to move a pointer, which is not something you do in any other context. The learning curve is real. Two weeks of deliberate practice is typical before it stops feeling awkward.

Neither is easier. They are just different, and the one you pick determines which muscles do the repetitive work. If your thumb already hurts from phone use or from gripping a mouse all day, a thumb trackball will make that worse. If you have finger or wrist pain from typing, shifting cursor control to those same fingers may not help.

The trackballs we stock and who each suits

Logitech MX Ergo S Advanced Wireless Trackball Mouse USB C

This is the high-end thumb trackball. It has a hinged base that adjusts the tilt angle from flat to twenty degrees, which changes how much your forearm rotates inward. At twenty degrees your hand sits in a more neutral position, halfway between palm-down and a handshake. That matters if you are already feeling forearm strain from pronation.

The ball is large enough that your thumb does not cramp, and the device includes a precision mode button that slows the cursor speed for fine work. Battery lasts about four months on a charge. It connects over Bluetooth or the included USB receiver, and it works across three paired devices with a button to switch between them.

The twenty-degree tilt is the reason to pay extra for this model over the M575S. If you do not need the tilt adjustment, you do not need this trackball.

Logitech Ergo M575S Wireless Bluetooth Trackball Mouse

This is the starter thumb trackball. It has the same thumb-operated ball as the MX Ergo S, but the base does not tilt and the device has fewer programmable buttons. It connects over Bluetooth or the included USB receiver, and the battery lasts about two years on a single AA cell.

The lack of tilt adjustment means your hand sits palm-down, the same as it would on a standard mouse. If that position does not bother you now, the M575S will feel immediately familiar. If you are trying a trackball specifically to reduce forearm rotation, the fixed angle defeats the purpose.

This is the model to buy if you want to try a thumb trackball without spending money on a feature set you may not use. If you adapt to it and later want the tilt adjustment, the MX Ergo S is the clear step up.

Nulea M501 Wireless Trackball Mouse Ergonomic Thumb Control

This is a thumb trackball with a vertical grip angle, somewhere between the Logitech models and a fully upright vertical mouse. Your hand sits in a handshake position with your thumb operating the ball from the side.

The vertical angle reduces forearm pronation more than the MX Ergo S does, but it also makes the device larger and harder to position on a crowded desk. The ball itself is smaller than the Logitech models, which some people find less comfortable for extended use.

The M501 suits someone who already knows they want a vertical hand position and has tried other ergonomic mice. It is not a first trackball.

Kensington Expert Trackball Mouse

This is a large finger trackball with a scroll ring around the ball itself. The ball is 55 millimetres across, larger than any thumb trackball, and it moves on low-friction bearings that let you flick it to scroll quickly across a screen.

Your hand rests on the desk beside the device, not on top of it, and you move the cursor by rolling the ball with your index and middle fingers. The four buttons sit in the corners, within reach of your fingers and thumb, and all four are programmable.

The Expert is the finger trackball to buy if you want a device that will last. The build quality is noticeably better than the Orbit or the ELECOM models, and the scroll ring works reliably where some competitors use a sensor that skips. It is also expensive and large, which makes it a poor first attempt.

Kensington Orbit Wireless Trackball with Scroll Ring

This is a smaller, cheaper finger trackball with the same scroll ring design as the Expert. The ball is about 40 millimetres across, and the device has two buttons instead of four.

The Orbit is portable in a way the Expert is not, and it costs half as much. The scroll ring is less smooth and the ball occasionally skips if you let dust accumulate on the bearings. It is fine for trying the finger trackball concept, but if you adapt and use it daily, you will want the Expert within six months.

ELECOM Huge Trackball Mouse

This is the largest finger trackball we stock. The ball is 52 millimetres across and sits in a sculpted base with a palm rest on the right side, though the device itself is ambidextrous in practice.

The Huge has eight programmable buttons, more than any other model here, and it includes a dedicated precision mode button that slows the cursor for fine adjustments. The ball moves smoothly and the bearings feel better than the Kensington Orbit, though not as refined as the Expert.

The size is the trade-off. This device is six inches across and takes up more desk space than most keyboards. It suits someone who has decided they want a finger trackball and has room for it.

ELECOM DEFT PRO Trackball Mouse M-DPT1MRXBK

This is a finger trackball with a more sculpted shape than the Huge, designed to fit your hand rather than sit flat. The ball is 44 millimetres across, smaller than the Huge or the Kensington Expert, and the device has eight programmable buttons.

The DEFT PRO sits somewhere between a thumb trackball and a flat finger trackball. Your hand rests on the device with your fingers curled over the ball, which some people find more comfortable than the flat posture of the Kensington models. Others find it restrictive.

This is a second trackball, not a first. Buy it if you have used a finger trackball for six months and know you prefer a more hand-on posture.

Precision work: are trackballs actually worse for it?

Yes, for most people, for the first six months. Pixel-level work—placing an anchor point in a vector path, aligning shapes in a design file, adjusting vertices in Blender—is harder on a trackball than with a mouse. The muscle memory you have built up over years of mouse use does not transfer. Small movements overshoot, and the feedback loop between your hand and the cursor takes time to rebuild.

Some long-term trackball users report no precision difference after six months of daily use. Others never regain the same level of control and keep a mouse nearby for detail work. There is no honest way to predict which group you will fall into.

For coding, writing and browser-based work, the precision difference does not matter. You are clicking buttons, selecting text and dragging windows, none of which requires sub-pixel accuracy. A trackball handles that workload from day one.

If your job involves CAD, detailed image editing or 3D modelling, a trackball is a risk. You may adapt and prefer it. You may not. The only way to know is to try one on a project that does not have a deadline, and accept that you might be slower for a while.

Cleaning and the bearing question, honestly

Trackballs collect skin oil, dust and whatever else is on your fingers, and that debris migrates to the bearings. After a month or two of daily use, the ball will start to skip or drag in one direction. This is not a defect. It is maintenance.

Cleaning a trackball means removing the ball—most models let you push it out from underneath or lift it straight up—and wiping the contact points with isopropyl alcohol on a lint-free cloth. The ball itself gets the same treatment. This takes about two minutes and fixes the skipping immediately.

You will need to do this once a month if you use the trackball all day, maybe every six weeks if your hands are clean and your desk is not dusty. It is not difficult, but it is not optional either. A mouse does not require this, because the sensor sits above the surface and does not touch it.

Some models use ruby or ceramic bearings, which are marketed as requiring less maintenance. In practice, the difference is small. The bearings still collect oil, and you still need to clean them. The ruby bearings in the Kensington Expert do feel smoother than the plastic bearings in cheaper models, but that is a feel preference, not a maintenance advantage.

The starter pick and the endgame pick

If you have never used a trackball and want to try one without committing money to something you might hate, buy the Logitech Ergo M575S. It costs half what the MX Ergo S does, it works the same way, and if you decide a thumb trackball is not for you, you are out less money. The lack of tilt adjustment is not a problem for a first attempt. You do not yet know whether you want it.

If you have used a thumb trackball for six months and know you want the tilt adjustment, the Logitech MX Ergo S is the clear upgrade. The twenty-degree tilt puts your forearm in a more neutral position, and the extra programmable buttons and precision mode matter once you are using the device all day.

For finger trackballs, the Kensington Expert is the one to keep. It is expensive and large, but the scroll ring works reliably, the build quality is better than the alternatives, and the 55-millimetre ball moves more smoothly than smaller models. If you are not sure whether you will adapt to a finger trackball, the Kensington Orbit is the cheaper entry point, but expect to replace it with the Expert if you stick with it.

The ELECOM Huge suits someone who has decided they want a finger trackball and values extra programmable buttons over a smaller footprint. The ELECOM DEFT PRO and the Nulea M501 are second trackballs, not first ones. Do not buy either until you know what you are looking for.

Do not buy a trackball if your job depends on pixel-level precision and you do not have time to adapt. Do not buy one if your thumb or fingers already hurt from repetitive use. And do not buy one expecting it to fix poor posture or eliminate strain on its own. It shifts the work to different muscles, which helps if those muscles are currently underused and the ones doing the work now are overloaded. If everything already hurts, a trackball is not the answer.

Common questions

How long does it take to get used to a trackball mouse?

Two weeks of daily use is typical before a trackball stops feeling awkward and you can work at normal speed. Precision tasks like selecting small UI elements or placing a cursor in a text field take longer, often four to six weeks. Some people adapt faster. Some never fully adapt and keep a mouse nearby for detailed work.

Are thumb trackballs or finger trackballs better?

Neither is objectively better. A thumb trackball keeps your hand in a mouse-like position and suits someone who wants minimal relearning but less arm movement. A finger trackball eliminates wrist deviation entirely and uses muscles you already recruit for typing, but the motor skill is more foreign and takes longer to learn. If your thumb already hurts, a finger trackball is the safer choice.

Can you use a trackball for gaming?

Not for anything that requires fast, precise aiming. First-person shooters, real-time strategy games with rapid unit selection, and action games with precise dodge timing are all harder on a trackball than with a mouse. Turn-based strategy, city builders, card games and most puzzle games work fine. A trackball does not have the same low-latency sensor and granular DPI adjustment that gaming mice offer.

Do trackballs help with RSI or wrist pain?

Sometimes. A trackball eliminates the forward-and-back arm movement and the wrist deviation that come with mouse use, which can reduce shoulder and wrist strain if that movement was causing the problem. But a thumb trackball shifts repetitive load to your thumb, and a finger trackball recruits the same fingers you use for typing. If those areas already hurt, a trackball may make it worse. It is not a universal fix.

Why do trackball mice cost more than regular mice?

Smaller production volume and higher mechanical complexity. A trackball has to support a large rolling element on low-friction bearings while keeping the device stable on the desk, which requires more precise manufacturing than a sensor sliding over a surface. The market is also smaller, so tooling costs are spread over fewer units. A high-end mouse and a high-end trackball cost about the same; it is the budget end where trackballs are more expensive.

How often do you need to clean a trackball?

Once a month with daily use, maybe every six weeks if your hands are clean and your desk is not dusty. Cleaning means removing the ball and wiping the bearings and the ball itself with isopropyl alcohol on a lint-free cloth. It takes two minutes. If you skip it, the ball will start to skip or drag, usually in one direction where oil has built up on a bearing.

Can you use a trackball left-handed?

Finger trackballs are ambidextrous by design. Your hand rests beside the device, not on top of it, and the ball works the same way regardless of which hand you use. Thumb trackballs are handed. The Logitech models are right-hand only. Left-handed thumb trackballs exist, but we do not stock them and the selection is limited.

Will a trackball work on a laptop or do you need a desk?

A trackball works anywhere a mouse works—on a laptop tray, on your lap, on a couch armrest. The advantage is stronger when you have limited desk space or when your keyboard is centred and a mouse would sit too far to the side. A trackball on a laptop tray does not require repeated pickup-and-reposition the way a mouse does when you run out of travel, which matters if you are working from a small surface.

Do you need special software to use a trackball?

No. Every trackball here works as a plug-and-play pointing device without installing anything. Logitech and Kensington both offer software that lets you reprogram buttons, adjust cursor speed curves and set up application-specific profiles, but it is optional. The default button mappings and cursor speed are usable out of the box.
