The first thing you will notice about the design of Logitech G900 Chaos Spectrum is how comfortable and light the gaming mouse feels in your hand. It measures only 3.80 oz (107g) which places it amongst the lightest gaming mice out there. Despite the lightweight, the Logitech G900 has a strong build and you will notice the high quality of the materials used. The Logitech G900 Chaos Spectrum is also equipped with a “metal spring tensioning system” that enables the right and left click buttons to give quick, crisp feedback and allows gamers more and faster clicks.

Between the left and right click buttons you will find the scroll wheel that looks hollow due to the weight trim that Logitech has done from every little piece of the gaming mouse, but it is actually quite sturdy metal wheel covered in textured rubber that clicks three ways.

Below the scroll wheel you will find a button that controls its resistance and two buttons to switch DPI levels on the fly, particularly convenient for FPS players.

Apart from the most standard buttons the Logitech G900 Chaos Spectrum is fitted with two pairs of thumb buttons placed on each side of the gaming mouse, due to its ambidextrous design. You can of course, program them the way you want depending on your dominant hand and disable the ones you don't feel like you will be using and might actually be on your way.

Probably one of the most favourite buttons of hardcore tournament players is the one to switch between profiles and in the case of Logitech G900 Chaos Spectrum this button is located at the bottom of the gaming mouse.

The design and placement of all buttons are pretty comfortable for both - palm and claw grippers. With its curved back and pointed front, the Logitech G900 Chaos Spectrum looks smart and elegant at the same time.

A little touch added is the possibility to choose between 16.8 million colours to change the lighting of the “G” logo and the light elements under the scroll wheel. If you are a Logitech fan and you have some more of the gaming gear offered by the manufacturer then you can match the lighting between the gaming mouse and your other peripherals.


The most remarkable feature of the Logitech G900 Chaos Spectrum that no competitor brand can beat so far is the performance while in wireless mode. The wireless gaming mouse can last between 24 and 32 hours of continuous play, depending on if you are using it with the light off or on and it needs only 2 hours to recharge.

The Logitech G900 Chaos Spectrum recharges while plugged into its 6 feet braided cable, and of course you can use it in the meantime as a wired gaming mouse. However what we are interested in is the wireless mode and Logitech G900 Chaos Spectrum offers you two ways of using it as a wireless gaming mouse. You can plug the dongle directly in your PC which is the most common connection type that other brands use as well, or attach the dongle to the cord and use it wherever you get the best reception.

By using the Logitech Gaming Software you can constantly check the battery life level, so you never run out of battery.

Of course this is not the only thing you can use the Software for. Once you install it, it will scan your PC for the games you have on it and create profiles for them. From then on, you can use the Logitech Gaming Software to perform a test of the tracking surface and adapt the gaming mouse for a better performance, assign commands and skills to the buttons, adjust the DPI settings for greater accuracy and play with the lighting as well.

Not to forget the outstanding PMW3366 optical sensor with a DPI range of 200 to 12.000 with  zero smoothing or acceleration.


We have tested the Logitech G900 Chaos Spectrum with all sorts of game genres and not surprisingly it delivered excellent performance in all of them although it is aimed for eSports lovers. We have taken it out for a spin with our favourite Battlefield: Bad Company 2, StarCraft: Wings of Liberty and World of Warcraft and it was a really nice to have a capable and accurate gaming mouse like the Logitech G900 Chaos Spectrum is.

We have also put to the test the manufacturer’s claim of a 1ms response in wireless mode and we can safely say that the Logitech G900 Chaos Spectrum is completely lag free when in wireless mode and now hardcore tournament players can go wireless without fear.


The Logitech G900 Chaos Spectrum is what you pay for. It is a versatile, comfortable and accurate wireless gaming mouse that can easily get to be the favourite gaming mouse of the most hard tournament gamers. You will certainly feel like you have made your best investment in a gaming mouse so far.
