The thumb grooves on each side of the mouse are excellently contoured (and have some light grooves for added grip) to give my thumb and pinky purchase. The easiest way to describe the holding the G900 is to say that it doesn’t feel like an ambidextrous mouse in my hand. The back hump of the mouse is ideal for either a palm or claw grip, and while the harsh angles on top look like they’d pinch your hand, I’ve never made contact with those spots in a month of use.
Logitech’s new pivot bar for its main mouse buttons creates the best feeling and sounding click I’ve ever used in a mouse. Sound definitely plays a subtle part in the “feel” of a click, in the same way that a car’s exhaust affects how we perceive its power (Ford actually engineered the 2008 Mustang to sound like it did on-screen in Steve McQueen’s Bullitt). The practical benefit to this design is that the click behaves consistently no matter where you click on the button. Because the click action comes from a metal pivot bar, not a piece of plastic flexing on a hinge point, there’s no variance in the way the plastic moves based on where your finger presses the button.
This is the kind of minutia that most of us will never notice or care about while we’re playing games, and the vast majority of the time, maybe it doesn’t matter. But it feels great. It feels crisp. I could use all kinds of other adjectives that would also apply to a fresh cucumber. The practical benefit is that no matter how fast I’ve tried to click with the G900, I’ve never had the button rebound with my finger and cause me to miss a click. It is the absolute polar opposite of the click in the worst gaming mouse I’ve ever used.
In my testing of the G900’s sensor (the same featured in Logitech’s G502 and the G303), I couldn’t detect any issues with acceleration or jitter, even at a high DPI setting of 8000. The mouse responds to tiny movements but doesn’t pick up microscopic readings from cloth mousepads the way some laser sensors do. And since there’s no cord when using the mouse wirelessly, its lightweight body can’t get jerked around by its cable.
I’ve already written about how Logitech designed the G900 and its 12,000 DPI sensor for wireless performance, and testing it with games like League of Legends and Unreal Tournament hasn’t revealed any issues for me in terms of performance. It simply feels great. Clicks are responsive. There’s no perceptible lag or stutter at the mouse’s 1 ms polling rate. This is anecdotal, but I landed a pretty sick headshot in Unreal Tournament. I recommend the feeling.
The G900’s battery life has been fantastic in the time I’ve used it. The mouse smartly goes to sleep after a short span of inactivity, but I’ve never experienced a perceptible bit of lag as I’ve woken it from sleep. It snaps to life and is ready to go. With its main LED disabled (a quick change in Logitech’s software), the mouse can operate continuously for a bit more than 30 hours. Sitting on my desk at work, I’ve charged the G900 about once per week.
If I designed the G900, there are tiny things I’d change. I’d likely add rubber thumb grips, a la the Razer Deathadder, to each side. Actually, that might be the only thing I’d change. The body design of the G900 is a step forward for Logitech, and its click mechanism and wireless performance are a step up for gaming mice, period. Those things add up to a mouse that’s worth $150, but a bit too expensive for the average gamer. If and when the price comes down, it’ll be the best gaming mouse, period.
