Logitech G900 Chaos Spectrum Gaming Mouse

It will be hard to look at other gaming mice after the “G” for amazing performance, yet tasteful refinement.

It’s been a while since I reviewed something like Logitech’s G900 Chaos Spectrum Professional-Grade Gaming Mouse. Sitting at the end-top is a little lonely, considering it costs double the price of most competitors at $149.99. But that price nets you plenty of tightly packed hardware into a semi-angular behemoth, and wealth of technological features – probably more than you’ll probably ever need.

“Unparalleled” is a good word to describe what the truly G900 represents — utterly flawless with few equals.

Now, imagine what your dream gaming mouse would look like and the G900 will probably be the first thing you picture. Logitech is usually low-key when it comes to design, most notably as peripherals makers began transforming their lineup into bolder, brasher, and overtly neon-lit weaponry. The G900 ease into the language as curvaceous forms partially surrender to protruding ribbed angles, mostly where the main click buttons and rubber-grip scroll wheel reside. The entirety however is made from an amalgamation of matte, rubber, gloss plastic materials for ergonomics — and because hardcore.

There is a grand total of 11 additional (and possible) buttons that are situated everywhere and just as customizable for ambidextrous functionality. By default, there are two macro buttons on the left side that rest perfectly under your right thumb, made of plastic gloss for differentiation. Lefties need not worry either because the right portion can be pieced together with identical buttons or all four buttons on both sides, and no tools are required since they are magnetically attached. The top middle sports two more buttons and a wheel lock switch that unlocks the notch bearing for free-spinning movement, a little less sophisticated than adaptive scrolling but the wheel itself can be physically clicked in either direction or pressed in.

Oh, and the G900 can be tethered or wireless, which is icing on the cake for people strapped for ample desk space. A bespoke micro USB cable (version 2.0) made to grip the G900 so it doesn’t come loose and active 2.4GHz receiver is included, lasting a whole day (24 hours) of constant use with the LEDs on and around 30 hours without the lightshow. Regardless of connection, the 1ms (millisecond) response time is standard across the board.

Of course, getting the “Logitech Gaming Software” is necessary to harness the non-mechanical bits of the G900. When installed you can adjust presets tailored to DPI sensitivity, and specific polling rates (input Hz pings) to better match input demands to actual processor workload. The G900 can also be tuned to alleviate the surface reflectiveness of your desk for better response, although we didn’t need to make extensive use of it during testing. And finally the LED lighting can glow in whatever pattern and color you what it to — which is pretty much expected from gaming mice nowadays. So you can have it your way with 16.8 billion colors that sporadically pulse with menacing radiance.


There’s a distinct weightlessness that many gamers should appreciate, and the honest thing I say is that the G900 feels hollow but not in a pejorative sense. Logitech trimmed the fat as both the click buttons utilize mechanical spring tensioners for instant feedback and click performance, that’s also comfortable on the fingers since the amount of force needed is significantly minimal. I applaud them for sticking to a semi-traditional form because the G900 molds to my hand quite nicely — a fantastic compromise between angular and clean.

Tracking out of the box can, and will do 40G acceleration at 300 inches per second. This is inherently faster than any hands can a move a mouse for aggressive gameplay before DPI settings, which offers between 200-12,000 levels. It’s worth mentioning again that the G900 is low latency in both wired and wireless modes, and not once did we experience any lag when eliminating the USB cords.

But when you factor in the 2.4GHz and the built-in PMW3366 sensor we expected nothing less with 1ms of accuracy, these are enthusiast-grade parts that will make any wireless mouse suitable for intense and critical action and MMOs of DOTA 2, Counter-Strike: Global Offensive, and Enter the Gungeon. We like not being shackled by USB, but admittedly, the battery life is rather middling with the LEDs turned on and needs improvement. You’d think 24 hours would be a lot of time but we only got 19 hours at best — although a smaller capacity powerplant would explain why the G900 is so light in your hand — and can fortunately be recharged in a couple hours time or overnight. So we won’t complain too much.

When I got acquainted with the G900 Chaos Spectrum Gaming Mouse it was apparent this is one of the most breakthrough, and yet, civilized mice I’ve ever tested. The mechanical click buttons alone are in a class of their own with a tastefully done chassis, and that’s before the stellar array of latency, modular, and connectivity options. The only other competition I can think of coming close is the Mamba Gaming Mouse from Razer, but we may never know as they didn’t follow up with me about reviewing one… ¯\_(ツ)_/¯

On that basis, Logitech G have intelligently outdone themselves; making it hard to look at other gaming mice with similar approbation now.
