The Evoluent VerticalMouse 3 has a patented shape that supports your hand in a relaxed handshake position, and eliminates the arm twisting required by ordinary mice.

Avoids forearm twisting for comfort and good health
The patented shape supports your hand in an upright neutral posture that generally avoids forearm twisting. Many users, including medical doctors, ergonomists and physical therapists, said the Evoluent VerticalMouse provides superior comfort and even relieved their wrist pain.

Comfortable and 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.

Powerful and intuitive driver
Evoluent Mouse Manager for Windows provides extensive but easy to use functionality for buttons through a simple and intuitive interface.
