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 G900 Chaos Spectrum. Featuring a 1-millisecond report rate and our highly optimized 2.4GHz wireless connection, Chaos Spectrum delivers incredible responsiveness for competition-level twitch targeting.
Pixel-precise performance
Chaos Spectrum 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 Chaos Spectrum 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 107g, 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 high-endurance gameplay
Chaos Spectrum features exclusive clock-tuning technology that significantly reduces power consumption, 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.
*Battery life up to 32 hours with lighting off, or 24 hours with default lighting.
Faster and more reliable
Chaos Spectrum clock-tuning technology maximizes speed and battery life while minimizing degradation commonly caused by temperature, humidity, aging and part-to-part variances.
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 the force required to click — enabling faster recovery after each click. In addition, this system helps ensure a lower, more consistent and predictable click force from click to click.
Control at your fingertips
Use Logitech Gaming Software to program your favorite commands and macros to each of the up to 11 buttons.
Choose from 16.8 million colors
Chaos Spectrum features two lighting zones that can be customized independently to match your style, system or environment. With Logitech Gaming Software, you can select from a spectrum of up to 16.8 million colors and synchronize lighting patterns and effects with other Logitech G devices.
Best of both worlds
Plug in the data and charging cable to seamlessly switch between wireless and wired modes without interrupting your game.

Pros: I bought this because replacing another G9X (my favorite mouse up until now) was going to be too costly. I was wary of a wireless mouse, but the included cable can be used as a permanent attachment, so I bit the bullet and thought I would try it. If wireless was not up to snuff, I would just plug the cable in and leave it. Boy, was I glad to be wrong, and have an awesome mouse besides. -No input lag in wired or wireless mode. At all. And I play at high sensitivities within a tiny (about 3.5-4 inches around at the extremes) movement area on all of the games I play. -Lightweight -Side button swapping to change it to left-handed (or just to add two more buttons on the opposite side of your thumb) -Battery life -Build quality is top-notch. The thumb buttons are not "mushy" like my G9X's -"Surface tuning" in the Logitech software -I don't use DPI switching on the fly, so being able to swap use the DPI buttons as a generic mouse button for extra functions was awesome -Free-scrolling on the wheel has its switch moved from an inconvenient spot (the bottom of the G9X) to the best logical spot (right behind the wheel)
Cons: I will have to nitpick here to come up with cons. -If you are a palm gripper, the side buttons may be just a tiny bit too far back for your liking. But we are talking millimeters here. -This is really digging, but it would be neat if I were able to pick a handful of colors for the lighting and have those cycle. As-is, you can have the full spectrum cycle, one color (with "breathing" option), or lights off.
Overall Review: It's at a pretty premium price point, but I don't regret a penny of my purchase. The G9X was legendary, but this is a worthy successor.
