Low surface friction Low surface friction surface provides minimal resistance to the mouse feet when making the small movements common to high DPI gaming: requiring less force to start or stop a movement and minimizing the chance of overshooting cursor placement. Consistent surface texture The consistent surface texture provides the sensor the optimal imagery for translating mouse movement into cursor movement: an improvement over often inconsistent or dirty table or desk surfaces. Matched to Logitech G sensors Using a surface texture closest to the optimal testing environment: G440 gives gamers access to the get the fullest Logitech G mouse sensor accuracy and precision. Stable rubber base High DPI gamers make very subtle hand movements and even the slightest shift in the gaming surface can interfere with precise cursor control. The rubber surface ensures a stable base for mouse movement.
