Trusted by top esports athletes
In high-pressure moments, latency can be the difference between winning it all or losing. With millions on the line, top esports professionals can depend on G903. Featuring a 1-millisecond report rate and our highly optimized 2.4GHz wireless connection, G903 delivers incredible responsiveness for competition-level twitch targeting.

Pixel-precise performance
G903 comes equipped with the PMW3366 optical sensor—widely regarded as the best gaming mouse sensor on the market. PMW3366 has zero smoothing, filtering or acceleration across the entire DPI range (200–12,000DPI), delivering exceptional tracking accuracy and consistent responsiveness at any speed. For even better accuracy and speed, use surface tuning in Logitech Gaming Software to tune the sensor to your playing surface.

Superior comfort and speed
Every component of G903 has been optimized to reduce weight while maintaining stability. Each element of the construction was analyzed and adjusted to remove milligrams wherever possible, from thin wall molding to a hollow “spoked” hyperscroll wheel design. The result is a wireless mouse that weighs in at only 110g, maximizing comfort over extended periods of use and delivering quicker response to motion.

Customizable to fit your hand and style
Fully-configurable button layout and ambidextrous design allow for left- or right-handed use that works with nearly any mouse grip style, including palm, claw and fingertip grips. For those who want a little extra weight, G903 comes with an optional 10g removable weight.

For high-endurance gameplay
G903 features exclusive clock-tuning technology that significantly reduces sensor power draw, so you can play for a continuous 32 hours — an entire competition weekend — on a single charge.* Battery Assistant in Logitech Gaming Software keeps you informed about your charge level and gives you an estimate of your remaining battery life.

Best of both worlds
Plug in the data and charging cable to seamlessly switch between wireless and wired modes without interrupting your game. Use the included USB adapter to keep your LIGHTSPEED USB transceiver nearby to quickly switch between wired and wireless modes.
