Ergonomic Comfort Trackball Mouse - Smooth 36mm Roller Ball

Our review of this ergonomic trackball shows it is best for users who spend long hours at a desk and want a stationary pointing device that reduces wrist motion. The single biggest reason to consider it is the roller bearing mechanism, which delivers a notably low-friction feel compared with typical ball trackballs. Setup is straightforward with a wired USB-A connection, and the thoughtfully angled design helps maintain a natural hand posture during extended use.

Key Features

• Steel roller bearing: The roller bearing provides friction-free ball operation for smooth, consistent tracking across typical desktop tasks.
• 36mm silver ball: The relatively large ball surface makes it easy to move the cursor across large screens with fewer rotations.
• Ergonomic 28 degree angle: The angled body supports a natural hand position to reduce wrist strain during all-day use.
• Interchangeable bearings: Bearings can be replaced with compatible ELECOM parts, extending service life without replacing the whole unit.
• Wired USB-A connection: A simple plug-and-play wired interface ensures reliable tracking without pairing or batteries.

Who It's For

This trackball is aimed at office workers, designers, and anyone who prefers a stationary mouse to limit arm movement. It suits users who value mechanical smoothness and a stable wired connection for predictable cursor control.

It is less appropriate for people who require wireless freedom or those seeking extremely high-end tactile feedback from premium ruby bearings, since replacement ruby bearings are not included and some users report mixed impressions of feel and scroll smoothness.

Pros & Cons
