COMFORT AND QUALITY. CUSTOMIZED.
G703 brings together supreme comfort, durability and performance with a comfortable design and rubber side grips for control. Customize your gaming experience with 10g optional weight and 6 programmable buttons.
POISED TO TRIGGER
Advanced metal-spring button tensioning keeps the primary left and right mouse buttons poised to trigger with less force, which means exceptional button feel, responsiveness and consistency every time you click.
LIGHTSYNC RGB
Game-driven, full-spectrum RGB lighting responds to in-game action, audio, and screen color, synchronizing across G gear. Customize lighting animations and effects from ~16.8M colors using Logitech G HUB gaming software, and personalize to match your rig.
