When I first held the Logitech G900, my immediate thought was that it was empty. It’s super-light, weighing only 107g, which is incredible for a wireless mouse. The Razer Mamba – not particularly heavy, by any means – weighs around a fifth more. Logitech's weight-saving strategy is so exteme, even the scroll wheel has been hollowed out and its innards replaced with a "spoked" design to help trim the fat.
If you know the G303 buttons then you know the G900 buttons, but the G900 feels even better to me because I don’t need to curl my fingers as much. All the buttons click excellently, even the sidebuttons feel nice and crisp.
My thoughts on the shape are mainly positive as stated above, however there is one point of critique for me, which is the gap between the mouse buttons and the mouse body. If you look at previous Logitech mice like the G402 and G502 you’ll see that they had a ledge to the sides of the buttons, so does my beloved ZA11 and FK1.
From my hands-on time with the G900 so far, I haven’t noticed a single issue with its wireless performance, and switching between wireless and wired mode takes about five seconds. Logitech took journalists to its lab in Switzerland to learn about how they designed the G900’s wireless sensor and protocol to perform flawlessly in even the noisiest 2.4GHz environment, and show how they tested that performance against other mice.
I got my hands on a G900 this week and the first thing I noticed after picking it up was just how light the thing was. I couldn't believe it. At 3.8 ounces (107 grams), it's noticeably lighter than most mice, wired or wireless. It has a striking symmetrical design, reminiscent of the Batmobile, that makes it useable for righties and lefties.
I think it’s obvious that my feelings towards the G900 are generally very positive. This mouse delivers on all its promises in a stunning fashion. The shape is great, the weight is relatively low, the performance is through the roof… Anything that could be criticized with this mouse is down to personal preference, but objectively this is the best you can get right now.
Coming from using a Logitech G402 Hyperion Fury — which, admittedly, is also overkill for my needs — I felt like the G900 nestled into my hand more nicely. I had no trouble getting it to work on Windows 10, especially since I already had the Logitech software installed. The G402 (without its cable) weighs about the same as the G900, but the lack of a cable made a huge difference in comfort, especially since my desk is pretty cramped.
The battery life isn’t particularly great by itself, but when you consider that the mouse has the features that it does, along with the convenient charging mechanism, it is a downside we can overlook. The biggest gripe we have with the mouse, and the one that will probably stop some folks from actually buying it, is the $149.99 price tag. That’s a hefty premium for what boils down to a luxurious way to control your cursor.Regardless, the extent to which this mouse is over-engineered is spectacular, and for that, hats off to Logitech.
The wireless performance is exceptional, but what’s really groundbreaking here is how Logitech made the mouse so light. Every component was redesigned to reduce weight without compromising on durability and it’s certainly worked. Considering most wireless mice have added weight compared to their wired counterparts, it’s certainly an achievement.
Logitech G900 Chaos Spectrum is not only the ultimate gaming mouse, but also an excellent option for non-gamers looking for cutting-edge performance. Its $149.99 price tag is in line with that of other top-shelf offerings in the segment, so, if you have such a budget, by all means go ahead and pick one up.
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.
We’re doubtful the G900 is the mouse that will make wired fans recant, but it does seem a capable device that will give gamers an alternative to the Mamba, which is the current champion of ultra-premium wireless gaming hardware. We were head-over-heels for the Mamba when we reviewed it last year, but if any company can give Razer a challenge, it’s Logitech.
