Precision trackball for PC and Mac users

The Kensington Expert Mouse uses Diamond Eye optical technology for smooth, precise cursor movement. A large ball delivers the control that has defined the category for more than 15 years. It is built for anyone who prefers a stationary pointing device over a traditional mouse.

Scroll Ring puts navigation at your fingertips

The award-winning Scroll Ring surrounds the ball so you can scroll without moving your hand. Optical tracking keeps motion consistent on most surfaces. No moving parts under the ball mean less friction and quiet operation during long sessions.

Soft wrist rest included for daily comfort

The supplied wrist rest supports the hand during extended use. Wired USB connectivity avoids batteries and pairing steps. The symmetrical shape suits left or right-handed users who want a fixed desktop footprint.
