Large size, 400 x 460 mm, for more space and mouse movement. Rubber base stays in place for intense gaming. Surface texture is optimized for Logitech G mice and peak gaming performance. Low Friction = High Speed G440 features ultra low surface friction, offering high DPI gamers an ideal surface for subtle hand movements and quick mouse gestures. The polyethylene surface allows the mouse to move even when applying minimal force, minimizing mistakes from overcompensation when starting or stopping. Consistent Surface Texture Heavy patterns and designs can interfere with sensor performance. G440 features a clean, consistent surface texture. This gives sensors better imagery for translating mouse movement into cursor movement, an improvement over inconsistent or dirty table and desk surfaces. Matched to Logitech G Sensors G440 can give gamers access to enhanced sensor accuracy and precision. G440 uses a surface texture comparable to the optimal testing environment for Logitech G mice. Stable Rigid Base The only thing sliding on G440 is your mouse. A natural rubber base is firmly bonded to the high-impact polystyrene core, keeping the rigid surface right on the desk where you put it.
