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 the previous-gen). HERO sensor delivers exceptionally accurate and consistent performance with zero smoothing, filtering, or acceleration from 200 to 12,000 DPI.

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

Quickly switch between HI and LO modes with the flick of a switch. G603 delivers peak performance in HI mode with a 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.

Dual connectivity with LIGHTSPEED and Bluetooth allows you to connect to and control multiple devices across platforms. Easily toggle between the two connected devices with a press of a button.

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 on performance for custom balancing. When the battery is at 15%, both the LED status indicator and Logitech G HUB will notify you before the critical moment.

The G603 wireless gaming mouse can be fully configured to match your preferences. G603 comes with 6 programmable buttons including on-the-fly DPI shifting through up to 5 sensitivity settings. Use G HUB to assign custom commands, configure macros (sequences of clicks and keystrokes to simplify in-game actions and quickly execute complex tasks), store configuration profiles in the onboard memory, and more.
