Performance & Conclusion
As you might expect from Logitech's latest flagship mouse, the G900 is chock-full of the latest and greatest tech, making it arguably the most advanced gaming mouse on the market today. Of course it also comes with a price tag that reflects this, but don't worry the G900 performs well.
The PMW3366 sensor wound up to the maximum 12,000-DPI setting is more mouse than I can handle on a 4K display, but it has to be said it still tracked well with no noticeable jitter on a range of surfaces. Turning the DPI down to what I consider a more usable setting, around the 3000 range, the G900 did great in every game tested. I also tested with the DPI turned down very low for image editing and the G900 was buttery smooth here as well.
Along with the impressive sensor performance, I liked the G900's highly responsive switches with their clicky feel and sound. The custom left and right switches also felt good, and having the option to remove them is very much appreciated.
The ambidextrous design is a nice feature though I wish there was an option to attach a thumb rest, much like there is on the G.Skill Ripjaws MX780.
When looking at battery life, my findings were in line with Logitech's own claims. If you are concerned about battery you will want to disable the RGB lighting as it does make quite a difference between charges.
Some reviewers have complained about the lack of a charging dock, which I find strange considering in the past I hated wireless mice that required a charging dock because I couldn't use them while they were charging and I honestly don't want a dock cluttering up my desk regardless.
The G900 solves that by becoming a wired mouse with a micro USB cable when its battery needs a recharge, which happens in about two hours.
In the end, all that really needs to be said is that the Logitech G900 Chaos Spectrum is without question the best gaming mouse I've ever used. It really is that good and we can see plenty of enthusiasts justifying the $150 entry fee.
Although we'd like to see extended coverage, Logitech's limited two-year warranty isn't that bad compared to the competition. Razer also supports its top mice such as the $150 Mamba Chroma RGB wireless for two years. The same is true of Mad Catz with its expensive $200 R.A.T. PRO X. So, rather than tear Logitech a new one over what is practically an industry standard, I will just say that it would be nice to see all peripheral makers offering at least three years of coverage on mice costing $150 or more.
Pros: Aggressive yet sleek design. Excellent build quality. Polished Logitech software. Lightweight body, comfortable ambidextrous design. Goes wired to recharge battery.
Cons: Expensive. The battery isn't replaceable and would ideally last longer between charges. The wireless receiver must be nearby and in line of sight for best results.
