Logitech G900 Chaos Spectrum is a top level wireless gaming mouse and therefore it is pretty expensive, however it packs in amazing hardware. From performance standpoint, Logitech G900 is incomparable mouse in the category of wireless mice, and its design is very slick.

None the less, it faces stiff competition from its deadly rival, Razaer Mamba or G602, and the question is, is it really fruitful to spend such a huge amount. Let us help you in deciding that through our detailed review.

Design & Ergonomics

For long, Logitech was unwilling to follow the trends of gaming peripheral industry of developing big & bold mouse design. That is in past! Now Logitech G900 will dominate your desks with its big, glowy and pointy looks. If you are looking for a mouse with desk appeal, you would not be disappointed. It’s body is curved with harder edges. It is ambidextrous, therefore it can be used by both left and right handed users. And this is not achieved at the cost of comfort, as both sides feels pretty fine. The mouse is ideal for Palm grip but It also work with claw and fingertips grip.

Despite of being light weight, it feels like well build. Its mechanical switches are tested with 20 million presses which is impressive. Its branded with Spectrum, i.e. glowing LED strips. If this seems familiar, it is because of identical Razer’s Chroma feature. Gamers now expect glowing mice (for some reason), and in elaborate ways, therefore we cannot blame Logitech for copying this.

You can customised G900 with 16.8 million colors, which can be selected through Logitech Software. Lighting patterns are also available, and breathing for instance makes light fade in/out in soothing manner.

Mouse Weight

When I held it for the first time, my immediate feeling was that it is empty. It is super light at 107 grams of weight. Low weight strategy by Logitech is very extreme, even scroll wheel is hollowed out and its innards is replaced with spoke design to trim the fat. Razer Mamba, which we are considering as G900 competitor, weighs around 125g.

Mouse Buttons

Left/right click feel solid, and actuation distance is very low, time between switch clicking and finger moving is extremely low.

It has 2 buttons on left, positioned perfectly below your thumb, if you are a lefty, don’t be afraid as buttons magnetically detach and you can move them to right side also which is pretty awesome. 4 more buttons are attached to either sides for macros.

Scroll wheel is on the top, coated in textured rubber and behind it is a switch to unlock wheel bearing, therefore instead clicking in increments, it can spin freely. This’s very satisfying especially when you are in working mode and scrolling massive documents. Behind this are 2 buttons for toggling through your DPI presets. Which is shorthand for mouse-sensitivity adjustment. Mouse power button is on underside.

Logitech G900 – Software

Logitech has its own configuration software with many options. You can adjust DPI by using buttons. You can modify polling rate.
You can also adjust mouse lighting, save lighting profiles and other defaults on mouse own on-board memory. This allow you to use it on any computer without making adjustments or logitech software.

Going deeper, Logitech includes tuning feature which allow you to input surface on which you are using this mouse. Software can adjust settings on mouse on the basis of reflectiveness of surface on which you are playing. Most players would not find this very useful, however if you are trying to minimise or maximise the performances, every little thing can help.

It’s possible to reassign buttons and set up macros to several tasks. If you want using different setups for different games, Logitech has this solution too. It allows you to assign different mouse profiles to definite titles, therefore when you load a game it automatically loads the right settings.


Its accuracy of tracking is very impressive for a wireless mouse, with no cursor jump, no matter what surface the mouse is on. Logitech buzzes high on its ability to reduce fear that wireless mouse is prone to lagging problem because of interference, and it is extremely difficult to test it in real-time condition. It can track 40 G acceleration, and up to 300 inches/second speed. This is fast enough for majority gamers so don’t worry about that.

But, what is more exciting than tracing is its low latency, i.e. 1ms report rate in both wireless and wired mode which is important as wireless mice are considered too laggy especially when it comes to pro or competitive gaming.

Logitech G900 speed is supported by 2.4 GHz wireless connectivity and PMW3366 sensor, the most favourite of passionate gaming world. About sensor it is important to say that DPI range of G900 is 200-12,000. In reality, most users can never venture past 3,000, some with higher resolution screens UHD or QHD may need higher, however it is quite unrealistic that anyone can actually play at 12,000.

Battery Life

Logitech claims 32 hours of continuous gaming, although this drops to 24 hours with mouse lighting ON. Although it cannot be said with guarantee, it will never die during long 16 hours gaming session. Ont he other hand, Mamba offers 72 hrs of gaming with 16 hrs guaranteed alteast.

In order to completely charge the mouse, it takes 3 hours, which is fairly quick. However likelihood is that most of the users will possibly have it plugged in overnight, therefore charging time isn’t any issue. The good thing is, you can play in wired mode also. If the battery is getting low you can simply switch between wireless and wired modes without any interruption.

Gaming with Logitech G900

We tried and tested it with many games, including League of Legends, Left 4 Dead 2, World of Warcraft, CS:GO and the likes. For Left 4 Dead 2 and Counter Strike, it performed perfectly. Low latency and precise tracking ability made headshots quite easy. If you are a FPS gamer then
G900 is definitely for you.

Logitech G900 appears as a great all-purpose gaming mouse. It work fine in MOBA/MMORPG games too like League of Legends or World of Warcraft. Good thing bout this mouse is it can be used for any type of game without any special setup. Moreover its comfortable design and light build meant that you will be able to enjoy for several hours with very little to no fatigue. Overall, Logitech G900 gaming mouse will be suitable for most if not all the game genres, however it may not suffice for gamers who prefer to map 20 keys on their mouse.


  • Comfortable and ambidextrous design to suit all users
  • Wireless as well as wired mode
  • Onboard memory
  • Excellent performance with 3366 sensor
  • Battery life is long (at least 16 hrs of continuous game play)

Logitch G900 performs excellently, and we can surely say that it is a one of the best mouse out there, essentially in wireless gaming mouse category. Its perfect sensor and ergonomic designs makes it one of a kind gaming mouse, which caters both left handed and right handed gamers.

If you really crave for something that has a tournament grade quality or simply looking for a wireless gaming mouse which makes no compromises like misinterpretation and lagging, Logitech G900 can easily win the title of Best in that category. For advance MMORPG who frequently improve their ranking through buying boosting services like LoL elo boosting, Logitech –G900 Chaos Spectrum is fully functional, customizable, versatile and comfortable, and equipped with the perfect sensor to easily take your game play to next level.

The only issue we can think of is its price which is around $150 which makes it “not for everyone”. Moreover there are some pretty solid options when it comes to wireless gaming mice like Logitech G700s or G603. However, to sum it up, Logitech G900 Chaos Spectrum is a complete package. its a perfect combiantion of Light weight, good design and precise performance.
