MX Vertical is an advanced ergonomic mouse that combines science-driven design with the elevated performance of Logitech’s MX series. The natural handshake position of MX Vertical reduces wrist pressure and forearm strain. The unique 57° vertical angle has been optimized for an ergonomic posture without compromising a pixel of performance. MX Vertical features a 4000 DPI high-precision sensor, resulting in 4x less hand movement and reducing fatigue. And the cursor speed switch allows you to instantly adjust DPI speed and accuracy with the touch of a button. MX Vertical stays powered for up to four months on a full charge – and gets three hours of use from a one-minute quick charge.
