Introduction

IGHTSPEED WIRELESS
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.

OUR MOST ACCURATE OPTICAL SENSOR
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.

LIGHTWEIGHT CONSTRUCTION
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 AMBIDEXTROUS DESIGN
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.

POWER-EFFICIENT TECHNOLOGY
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.

WIRED AND WIRELESS
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.

POWERPLAY™ WIRELESS CHARGING-COMPATIBLE
Infinite power. Unlimited play.
Logitech G has realized the next era of gaming. And, it’s wireless. We’ve proven the ability to deliver unbeatable gaming precision, speed and lag-free wireless performance in the award-winning G900 and G403 gaming mice. Now, we’re removing charge time from the equation. Add POWERPLAY*, the world’s first and only wireless gaming mouse charging system, to keep G903 and G703 charged while at play and at rest.

CUSTOMIZABLE WEIGHT
Optional weight module
G903 comes with an included optional 10g removable weight module so you can customize the weight of the mouse to your preference when you aren’t using the POWERPLAY charging system.

EXCLUSIVE CLOCK-TUNING TECHNOLOGY
Faster and more reliable
G903 clock-tuning technology maximizes the top tracking speed speed and battery life while minimizing degradation commonly caused by temperature, humidity, aging and part-to-part variances.

MECHANICAL PIVOT BUTTON DESIGN
Fast, accurate and reliable click performance
A metal spring tensioning system and metal pivot hinges are built into left and right mouse buttons for a crisp, clean click feel with rapid click feedback. This system helps reduce the pre-travel distance between buttons and switches while also reducing bounce back—enabling faster recovery after each click. In addition, this system helps ensure a lower, more consistent and predictable click force from click to click.

ONBOARD MEMORY
Save your settings
With onboard memory, you can take your settings with you wherever you go. Save your settings to the memory on the mouse and use your settings on any PC without needing additional software or requiring a login to use them

11 PROGRAMMABLE BUTTONS
Control at your fingertips
Use Logitech Gaming Software to program your favorite commands and macros to each of the up to 11 buttons.

PROGRAMMABLE RGB LIGHTING
Choose from approximately 16.8 million colors
Brilliant RGB lets you customize lighting brightness and color to match your style, system and environment. With Logitech Gaming Software, you can select from a full spectrum of approximately 16.8 million colors and synchronize lighting patterns and effects with other Logitech G devices.

PROGRAMMABLE DPI SETTINGS
Fine-tuned control
On-the-fly DPI shifting that lets you program and switch between up to 5 sensitivity settings, from pixel-precise targeting (200 DPI) for sniping, to lightning-fast maneuvers (up to 12000 DPI) for fast 180-degree turns
