The Kensington Expert Trackball ambidextrous mouse design, works equally well for either

right handed or left handed users while taking up less desk space.

Surrounding the ball, the scroll ring lets you scan up and down the screen, with ease.

The large ball and scroll ring reduce hand and wrist movement and offer precise fingertip control while scrolling.
