Wireless LIGHTSPEED - The mouse of choice for top Esports players
In heated situations, the amount of delay can mean the difference between victory and defeat. When millions are at stake, the best Esports players can count on the G903 mouse. With a 1ms reporting rate and optimized 2.4GHz wireless technology, the G903 has incredible sensitivity for competition-level fast targeting.

Our most accurate optical sensor - Pixel-accurate performance
The G903 features the PMW3366 optical sensor, considered by many to be the best sensor on the market for a gaming mouse. The PMW3366 has zero smoothing, filtering or acceleration across the entire 200-12,000 DPI range, providing exceptional motion tracking and consistent sensitivity at all speeds. For even greater accuracy and speed, use Logitech Gaming Software to calibrate the sensor to the surface you're using.

Lightweight construction - Excellent comfort and speed
We tried to reduce the weight of every element of the G903, while maintaining stability. Every element has been analyzed and redesigned in order to save milligrams wherever possible - whether it's a thinner cover or the high-speed scroll wheel with a hollow "spoke" design. The result: a wireless mouse weighing only 110 grams, which provides maximum comfort even during long use, and which reacts faster to individual movements.

Customizable ambidextrous design - Adapts to your hand and style
The fully configurable button layout and ambidextrous design allow you to use it with either your right or left hand, with any grip, be it palm, fist or fingertips. And for those who want a little extra weight, the G903 has an optional, removable 10-gram fine-adjustment weight.

Energy efficient technology - Designed for long use
The G903's unique new clock tuning technology significantly reduces the sensor's power consumption, allowing you to play for up to 32 hours (a full race weekend) on a single charge. Logitech Gaming Software's Battery/Battery utility provides information on charge and approximate remaining battery life.

Wired and wireless - The best of both worlds
Connect the data and charging cables to seamlessly switch between wireless and wired mode without interrupting your game. With the included USB adapter, you can keep the LIGHTSPEED USB adapter nearby to quickly switch between wired and wireless mode.

Compatible with POWERPLAY™ wireless charging system - Endless power supply. Unlimited play.
Logitech G has created the next era of gaming. In fact, it's even wireless. With the award-winning G900 and G403 gaming mice, we've proven our ability to deliver unbeatable gaming precision, speed and lag-free wireless performance. Now we remove charge from the equation. Using the world's first and only gaming mouse POWERPLAY wireless charging system, the G903 and G703 stay charged while playing and resting.

Customizable weight - Optional fine adjustment module
The G903 has a 10 gram removable fine adjustment weight module so you can tailor the weight of the mouse to your needs. When not using the POWERPLAY charging system

Unique clock tuning technology - Faster and more reliable
The G903's clock tuning technology maximizes motion tracking speed and uptime while minimizing degradation due to temperature, humidity, aging, and individual wear.

Mechanical rotary button design - Fast, accurate and reliable click performance
The metal spring tension system built into the right and left mouse buttons and the mechanical pivot design ensure a crisp, clean click feel and quick click feedback. The system reduces the distance between the button and the switch, as well as the recoil - this way, after one click, you can prepare for the next click as quickly as possible. What's more, thanks to the system, you should exert a smaller, more uniform and constant click force with each click.

Built-in memory - Save settings
With the help of the built-in memory, you can take your settings with you everywhere. Save your settings to the mouse's memory and use them on any computer without having to install additional software or log in anywhere.
