Prestige International Evoluent VerticalMouse 3 Right Hand Handshake Grip Mouse, Silver/Black

The Evoluent VerticalMouse is the advanced third generation of the revolutionary mouse from the inventor of the handshake grip. The patented shape supports your hand in a fully upright handshake position that eliminates forearm twisting. 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 into a handshake position. Many users said they got used to it very quickly. The VerticalMouse does not move sideways when clicking with normal force because the thumb naturally opposes the fingers. Pointer control is as accurate as any other good mouse when the pointer speed settings are properly adjusted.
