G603 Wireless Gaming Mouse


Play Without Limits

G603, with the revolutionary HERO sensor and LIGHTSPEED wireless technology, delivers exceptionally accurate and consistent performance and a breakthrough in battery life setting a new standard in wireless gaming.


Next-Gen Hero Gaming Sensor

HERO is a revolutionary new optical sensor designed by Logitech G to deliver class-leading performance and up to 10 times the power efficiency (compared to previous gen). HERO sensor delivers exceptionally accurate and consistent performance with zero smoothing, filtering or acceleration from 200 to 12,000 DPI.


Lightspeed Wireless

Through end-to-end engineering and design, Logitech G developed a robust wireless solution to solve the fundamental problems of latency, stability, and connectivity. The end result is LIGHTSPEED, a pro-grade wireless solution, that achieves wired-like performance.

Advanced Power Management

Quickly switch between HI and LO modes with the flick of a switch. In HI mode, G603 delivers peak performance with LIGHTSPEED 1ms report rate and up to 500 hours of non-stop gaming. When not gaming, simply switch to LO mode and extend battery life. LO mode reports at 8 ms for up to 18 months of use with 2 AA batteries.2Battery life may vary based on user, battery discharge characteristics and computing conditions

Amazing Battery Life

G603 wireless gaming mouse delivers up to 500 hours on 2 AA batteries—twice as long as our previous generation. Even with a single battery the G603 can last through up to 500 matches of League of Legends®. You can also choose which side to place a single battery with no impact to performance for custom balancing. When battery is at 15%, both LED status indicator and Logitech Gaming Software (LGS) will notify you before the critical moment.

Six Programmable Buttons
