The patented shape of the Evoluent VerticalMouse Standard supports your hand in an upright neutral posture that generally avoids forearm twisting.


Benefits
· Comfortable and easy to use. The shape is thoughtfully sculpted for comfort and easy-to-reach buttons.
· Contoured thumb rest. The thumb rest is positioned to support the thumb at the proper height.
· Finger groove prevents rubbing. A contoured groove along the bottom edge prevents the last finger from rubbing the desk and enables the mouse to be easily lifted.
