From the manufacturer

The “hand-shake” grip helps reduce muscle stress and the 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 1000, 1200 to 1600 DPI.

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.

Up to 10 million times life cycle.
