The Evoluent VerticalMouse 4 has a patented shape that supports your hand in a relaxed handshake position, yet requires no adaptation period. The design eliminates the muscle tension created in the forearm, neck, and shoulder by other mice. Once you experience the superior comfort of this ergonomic pointing device, you will never go back to an ordinary mouse.
Eliminates Arm Twisting
The patented shape supports your hand in a relaxed handshake position that eliminates forearm twisting. You will quickly become accustomed to the improved comfort.
An ordinary horizontal mouse requires your forearm to twist away from its natural position.
Comfortable & Easy to Use
The shape is thoughtfully sculpted for uncompromised comfort and easy-to-reach programmable buttons. No finger contortions are needed to operate the buttons.
Improved Thumb Rest
The thumb rest has been reshaped to provide even more comfort over earlier versions.
Two Thumb Buttons
A new bottom thumb button provides greatly extended functionality when used with the included driver.
Compatible Operating Systems
