The Evoluent Mouse has a patented new shape that will support your hand in a relaxed handshake position, eliminating the arm twisting required by ordinary mice. It is a major advance in mouse evolution.
The Evoluent Mouse is perfect for people who find the 'Handshake' position more comfortable than the normal mouse position. A standard Horizontal mouse requires your forearm to twist, which is not its natural position. Holding your hand in a fully upright position that eliminates forearm twisting, the Evoluent Vertical mouse improves comfort, increasing productivity.
