Keyovation Vertical Mouse 4, Right Hand

This truly ergonomic mouse avoids forearm twisting for your comfort. The patented shape supports your hand in an upright neutral posture that generally avoids forearm twisting. The shape is thoughtfully sculpted for uncompromised comfort and easy-to-reach programmable buttons. No finger contortions are needed to operate the buttons. Pointer speed controls on the side allow convenient adjustment without even releasing your grip from the mouse. The thumb rest has been shaped to provide more comfort over earlier versions. Top mounted LEDs show through the chrome thumb rest to indicate selected pointer speed including extra low (XL), low (LO), MD (medium), to high (HI). A bottom thumb button provides greatly extended functionality when used with the included driver. An extra wide lip along the bottom edge prevents the last finger from rubbing the desk.
