Evoluent VM2-LSB VerticalMouse 2 Optical Left Hand - Silver/Black

The Evoluent VerticalMouse 2 supports your hand in a relaxed handshake position and eliminates arm twisting. Once you experience the superior comfort, you will never go back to ordinary mice. An ordinary horizontal mouse requires your forearm to twist away from its natural position. The grip is the same as an ordinary mouse, just turned sideways, and the buttons are operated by the same fingers. Pointer control is as accurate as any other good mouse.

Reduces Hand Movements:1200 DPI true Optical Resolution sensor moves the pointer quickly to reduce hand movements. The pointer can be moved across a 17" Monitor with only 1/2" (13mm) movement of the mouse. Most other mice have 400-800 dpi and require more hand movement.
