The vertical ergonomic design ensures a natural and tension-free hand position, actively supporting longer work sessions at the PC. In addition to the large-sized buttons, the three-level adjustable sensor (up to 1600 dpi) allows for precise work at the push of a button. The ON/OFF switch located on the bottom provides the option to deactivate the mouse after use. The high-quality silk-touch coating and the integrated 2.4 GHz USB nano receiver complete the overall picture of the vertical mouse.
