Logitech G900 Chaos Spectrum Review

After more than a month of using the Logitech G900 Chaos Spectrum as my daily work and gaming mouse, I can’t find a single flaw or thing to dislike about Logitech’s new wireless flagship. It’s incredibly light for a wireless mouse (and light for a gaming mouse, period, at 107 grams), has a fantastic shape that contours to my hand despite being an ambidextrous design, and hasn’t shown a single sign of jitter, stutter, or wireless failure in the time I’ve been testing it. It’s the best gaming mouse I’ve ever used, with only one drawback: to accomplish the feat of engineering that is the G900, Logitech made a $150 mouse, double or triple the price of the best wired mice that exist today.

Setting aside the value conversation for a minute, the Logitech G900 Chaos Spectrum is a feature-packed gaming mouse that would be ambitious even before you factor in the complexities of wireless gaming mouse. The 107 gram weight is targeted at players who, like pro gamers, want a light mouse to operate as an extension of their hand, not a heavy object that you sling across a pad. Despite that weight, the G900 doesn’t feel fragile or cheap. There’s no flex in the plastic if you squeeze it.

Logitech’s signature metal Hyper scroll wheel is still there, now cored out to weigh a few grams less. The wheel still spins freely for 15 seconds or delivers a satisfying notched scroll depending on the mode you have it set to with a quick button press. The wheel also clicks side-to-side for two more button inputs, one of my favorite features of past Logitech mice. I don’t use it for gaming, but I love it as a web browser forward-and-back keybind.

The two real stars of the Logitech G900 Chaos Spectrum are its ambidextrous body and its newly designed hinge for the left- and right-click buttons. Ambidextrous designs usually result in a shape that’s not as ideal for a right-handed grip. As a lefty myself, I’m sympathetic to gamers who want a great gaming mouse designed for their left hand, but as I grew up under the vicious thumb of the public education system, I long ago learned to use a mouse (and scissions) with my right hand. While there are ambidextrous shapes out there that many players swear by (often because they’re small, lightweight mice) like the Steelseries Sensei, I often find myself mis-clicking the buttons on the right side of the gaming mouse, or wishing my thumb and pinky had unique grooves or grips designed to support them.

Those issues don’t crop up with the Logitech G900 Chaos Spectrum. A pair of thumb buttons on each side of the mouse can easily be removed or attached using magnets, and the G900 ships with blank pieces to fill in the button slots for your off hand. Despite attaching with magnets, I haven’t had any problem with the click activation of the buttons or their ability to stay attached to the mouse. Their size and placement is also a welcome improvement over Logitech’s last model, the G303, which made its thumb buttons a bit too small and thin.

Unlike previous Logitech mice, such as the G502 Proteus Spectrum and the G303 Daedalus Apex, the G900 is not based on any pre-existing mouse design. As such, it sports a distinctive appearance that complements how supremely comfortable it is, regardless of your dominant hand. Logitech G900 Chaos Spectrum  is a small, light, symmetrical gaming mouse(5.12 x 2.64 x 1.57 inches, 130 x 67 x 40 mm, 3.77 ounces) with a thin body and subtle indentations to rest the thumb and outermost fingers. The only big flourishes are two “fins” at the bottom of the left and right buttons, which look cool but don’t have any effect on gameplay or grasp.

Speaking of buttons, Logitech G900 Chaos Spectrum has anywhere between five and nine, depending on how you want to configure it. Because the gaming mouse must cater to both dexterous and sinistral players, it also gives them the ability to swap out thumb buttons. Ambitious gamers can have thumb buttons on both sides, while extremely conservative ones can eschew thumb buttons entirely. This solves a neat and very real problem facing other ambidextrous gaming mice: Even if you disable nondominant thumb buttons, you usually wind up clicking them a lot, which can get annoying.

Aside from the thumb buttons, the G900 possesses a left button, a right button, a scroll wheel that clicks three ways, and two dots-per-inch (DPI) sensitivity buttons in the center that users can also reprogram if they don’t need to change DPI on the fly. All of the buttons feel fluid, responsive and well placed.

There’s also a button to change the resistance of the scroll wheel (itself a metal contraption with a pleasant rubber coating) and one on the bottom of the mouse to change profiles. This may not sound very useful for the everyday gamer, but for tournament players who plan to take the G900 from place to place and don’t want to reinstall the Logitech Gaming Software each time, it can be a lifesaver.

Like Razer, Logitech has its own software for configuring the G900’s many options. For instance, you can adjust the DPI presets so you’re using the buttons only to switch between comfortable levels of sensitivity. You can also modify the polling rate – how often the mouse pings the computer – to 125Hz, 250Hz, 500Hz, and 1,000Hz. This feature is fairly niche, but handy if your PC’s processor isn’t up to the task of handling 1,000 inputs every second.

You can adjust lighting for the mouse too. You can save lighting profiles – and your other defaults – to the G900’s on-board memory, making it easy to use the mouse on different computers without having to adjust the settings each time.

I tried Logitech G900 Chaos Spectrum on a number of games, including World of Warcraft, League of Legends, Left 4 Dead 2, and Counter-Strike: Global Offensive.

For L4D2 and CSGO, the Logitech G900 performed excellently. The low latency and accurate tracking made tearing off the heads of zombies and terrorists alike a breeze. It’s certainly the best mouse I’ve ever used for first-person-shooter gaming, so if you need a hardcore FPS gaming mouse, the G900 is a fantastic buy.

The G900 proved a great all-rounder, too, working just fine in League of Legends (MOBA) and World of Warcraft (MMORPG). The fact that the G900 isn’t bogged down by hardware faff makes it easy to play any game without much setting up. What’s more, the light build and comfortable design meant that I was able to play League of Legends for hours on end with very little fatigue. And I click a lot.

Perhaps one of the few downsides of the Logitech G900 is that it doesn’t have many buttons. That won’t annoy everyone, but some MMO players that are used to 18-button spreads might find the minimalism frustrating. Still, the performance is better than alternatives, so it’s a trade-off I think such MMO gamers will be willing to make.

All in all, the Logitech G900 will suit most game genres, but it won’t suffice for those who prefer to map 20 different keys to their gaming mouse.


The Logitech G900’s performance is excellent, and I daresay class-leading and the design is among the most sensible and refined that I’ve ever come across in a gaming mouse.

What you probably want to know is whether you should opt for this or the Razer Mamba (2015). After all, they’re the same price, they’re effectively the same proposition, and they’re both damned good products.

For me, the Logitech G900 edges out, if only slightly, over the Mamba. The performance – in terms of tracking, latency, and connectivity – is simply superior to the Mamba, although not by a long way. I’d still argue that the Razer Mamba (2015) sits a little more naturally in the hand if you’re a righty, but Logitech wins out on hardware overall.

In all honesty, both mice are excellent, and you won’t regret buying either one of them. I personally prefer the Logitech in terms of feel, although the Razer Mamba is better value with its dock and customisable hardware.

If you crave tournament-grade quality, or simply want a wireless mouse that makes no compromises, the G900 is about as good as gaming mice get. It’s comfortable, customizable and versatile, and it knows exactly what it wants to be. Most players simply don’t need to dish out $150 for a mouse, particularly when they can get an excellent all-purpose peripheral, like the Proteus Spectrum ($80), for about half the cost. But gamers who are willing to pay a premium price will love what they get in return.
