Logitech G703 Lightspeed Wireless Gaming Mouse HERO 25K 95g Black

Right-handed gaming mouse

The Logitech G703 Lightspeed is a right-handed wireless gaming mouse that weighs 95 g and uses a HERO 25K optical sensor with 100 to 25,600 DPI and 400+ IPS tracking. It connects through 2.4 GHz LIGHTSPEED wireless or a wired USB link and includes six programmable buttons with metal-spring tensioning on the primary switches. Rubber side grips and a removable 10 g weight let each user adjust balance and feel.

Upgrade from wired or lower-sensor mice

The jump is worth it when a cable snags during fast swipes or when an older sensor adds smoothing that throws off muscle memory. HERO 25K removes smoothing, filtering and acceleration while delivering 10x the power efficiency of the previous generation, so the same 35-hour battery life covers far more effective tracking. POWERPLAY compatibility adds continuous charging for sessions that run past a single battery cycle, though the charging mat is sold separately.

Simple USB setup with optional weight tuning

Plug the LIGHTSPEED receiver into any USB port and the mouse pairs instantly; no driver is required for basic function. G HUB software unlocks DPI steps, button mapping and 16.8 million-colour LIGHTSYNC RGB effects. The only common snag is forgetting the 10 g weight inside the cavity when a lighter feel is wanted, or leaving the receiver in a rear port that blocks line-of-sight on metal desks.
