Is the Kensington Expert Wireless Trackball worth it?

Yes, for the right buyer. The Kensington Expert Wireless Trackball ranks #3 in our Best Ergonomic Mice 2026 list (best trackball). Its biggest strength: wrist does not move during cursor control, only fingers move the ball. The main caveat: trackballs require a different learning curve than standard mice, more than vertical mice.

Overview

What the Kensington Expert Wireless Trackball does well

Best trackball for RSI prevention. It stands out for wrist does not move during cursor control, only fingers move the ball and ambidextrous design works equally for left and right hand. One caveat, trackballs require a different learning curve than standard mice, more than vertical mice.

The Kensington Expert is the most recommended trackball for office ergonomics because it solves the problem of repetitive hand and arm movement completely. The scroll ring is genuinely superior to a scroll wheel for document work. The 2 to 4 week adaptation period is real but worth the investment for users with chronic RSI from volume of movement.From our full Kensington Expert Wireless Trackball review

What hand size do I need for a vertical mouse?

Most vertical mice (Logitech MX Vertical, Anker Vertical) are designed for medium to large hands, 17 to 20cm hand length. If your hand is under 17cm, these mice will position your thumb in an awkward forward reach and reduce button control. Look for compact vertical mice specifically sized for smaller hands, or consider a trackball, which eliminates grip altogether.

Are trackball mice better than vertical mice for small hands?

Trackballs have one ergonomic advantage for small hands: the hand rests flat or in a neutral position without needing to grip a shaped body, so hand size matters less. A thumb-operated trackball (Logitech MX Ergo) positions the thumb actively, which can strain small hands. A finger-operated trackball (Kensington Slimblade, Kensington Expert) distributes the tracking motion across the fingers rather than concentrating it in the thumb.
