HERO 25K SENSOR
Meet the next-generation HERO 25K Sensor, our most advanced sensor ever, with 1:1 tracking, 400+ IPS, and 100-25,600 max DPI sensitivity — plus zero smoothing, filtering, or acceleration.

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 G HUB gaming software, and personalize to match your rig.

SUPREME COMFORT AND QUALITY
G403 is lightweight and comfortably designed to mold to your hand with rubber grips for added control. An optional 10 g removable weight lets you tune the weight to your preferences.

G HUB
Configure 6 programmable buttons using Logitech G HUB software to simplify in-game actions. Customize your DPI sensitivity setting from 100 - 25,600 DPI. Choose pixel-precise, low-sens targeting to lightning-fast maneuverability.

ADVANCED GAMING PERFORMANCE
With a 1ms response time, G403 is up to 8x faster than standard mice not designed specifically for gaming, delivering near-instantaneous moves and clicks. G403 also features advanced metal-spring button tensioning, keeping the primary left and right mouse buttons poised to trigger with less force. That means exceptional button feel, response, and consistency with every click.
