Kensington Slimblade(TM) Trackball Mouse

Slimblade Trackball Mouse, Bluetooth connectivity Finally, a mouse that works everywhere.

The Kensington SlimBlade Trackball Mouse works where other travel mice can't. The trackball gives you control even when there's no room to move a mouse, then switches to mouse mode with the push of a button. Bluetooth® connectivity offers up to 9 metres of range and doesn't use up a USB port.
