MX Vertical is an advanced ergonomic mouse that combines science-driven design with the performance of Logitech’s MX series. The natural handshake position has been proven to reduce wrist and forearm strain related to repetitive strain injuries (RSI), and the unique 57 degree vertical angle has been optimized for an ergonomic posture without compromising a pixel of performance. MX Vertical has a 4000 DPI high-precision sensor resulting in four times less precision errors. The cursor speed switch allows you to instantly adjust DPI speed and accuracy with the touch of a button. Stays powered for up to five months on a full charge, with just one minute of quick charge lasting for three hours.
