Features

Reduces Carpal Tunnel Syndrome (CTS)

The “hand-shake” grip helps reducing muscle stress and risk of Carpal Tunnel Syndrome. The vertical design provides better support for your forearm minimizing wrist pain that can come from twisting.

Adjustable cursor moving speed from 800, 1200 to 1600 DPI.

Two internet navigational buttons, back and forward, are conveniently located on the left side of mouse to provide you with internet browser control with minimal hand movement.

Tracks accurately and precisely on different surfaces, like marble, wood and leather surfaces.

The wrist-friendly contour of the Adesso vertical mice allows you to hold your hand in a neutral “handshake position”, minimizing your forearm muscles from twisting and the possible development of Carpal Tunnel Syndrome. Normally, your forearm muscles are twisted from sitting flat on the supporting surface when using a regular mouse. This “flat position” causes strains on your muscles and leads to wrist pains. This is where the Adesso Vertical Mice become helpful and provide alleviation.
