The Logitech Cordless TrackMan Wheel mouse combines a cordless trackball with advanced optics and digital radio technology - all in the palm of your hand. The stylish design puts the trackball under your thumb with the scroll wheel and buttons at your fingertips.

Advanced digital radio signal needs no line of sight and lets you work up to two metres from the receiver - through cups, piles of papers or the thickest sandwich. In addition, patented optical technology delivers precise and smooth tracking.

Connectivity: RF technology via USB
