Logitech G900 Chaos Spectrum Professional Grade Wired/Wireless Gaming Mouse (910-004558)

100% Positive Reviews
Rated #24 in Mice


Pros: Fastest Wireless Mouse available, Robust Software/Onboard settings, Supreme Consistency.

Cons: The clicks are too stiff for small hands, The feets don't glide as much as my Sensei Wireless, there's no alternative for smaller hands.

This is the best mouse you can buy today but it might not be for you, and I will explain why in a second.

Let me begin by saying that I've owned several gaming mice, from the Logitech MX Performance to the G700s, from a Roccat, Zowie, fierce gaming no brand mouse to a Steelseries Sensei wired and Wireless and have also owned the best Mousepads in the market, Destructor II, Manticor, Steelseries DeX, Artisan Shidenkai MID even a sheet of pure HDPE plastic for maximum possible glide, coated with Pledge... Yeah I know.

I bought this mouse to replace my Sensei Wireless which I loved but then replaced with a Razer Mamba which I dreaded, I was worried that this Mouse would just be the jumbo mumbo marketing and the shouts of "The most advanced gaming mouse" just like the mamba Chroma 2015 was, I even shrug to the thought that people really said that about the Mamba, those fears were all gone after a mere hour of use.

Let me begins with the Pros.

1-) The Wireless, I kid you not, is extremely fast, I watched all the videos showing up the benchmarks comparing the G900 against the competition, but I had to test this myself in the real world, Boy was I impressed.

I've always used Human Benchmark reaction time, when using the Razer Mamba Chroma 2015 my average was 215ms in Wireless mode and 190ms in Wired Mode.

Using the Logitech G900 I managed 180ms AVERAGE of the first 5 tries which is absolutely incredible, completely obliterating the Mamba even when using it Wired, my Sensei Wireless had better performance than the Mamba as I managed 210ms Average wireless, but even that score was obliterated by the G900.

2-) -The shape is good for a palm grip and decent for claw just like an enlarged less curved Sensei, more similar to the Proteus Core but with many differences, for example the G900 Chaos do works way better for Fingertip and Claw grips than the Proteus core while still retaining the Palm Grip ergonomics.

3-) The lights are minimalist and design is very professional with just enough gaming poured into it.

4-) I've been using it for some time now and its 100% consistent, not even the Microwave can disturb the signal on this Mouse.

5-) Unlike Razer Failnapse the LGS is a Blast to use, it works extremely well, its simple and powerful, the surface tuning software works extremely well with native surface tuning instead of Software based tuning like on the Razer Mamba which doesn't work nearly as well.

6-) The onboard Memory: Unlike the Sensei Wireless and the Razer Mamba you don't need the drivers to make the Mouse work the way you want it, you just need the drivers to change the settings.

On the G900 you set your macros and profiles once in the software and then you can proceed to uninstall it, all of your settings will be saved in the G900's Onboard Memory, meaning that you will get a 100% consistent experience when using it on any PC, be it your friend's or a tournament.

There's two small buttons beneath the Scroll wheel to rise or lower the DPI steps you already saved on the Onboard Memory, at the bottom of the mouse just next to the sensor there's a pretty button you press to swap the profiles you already saved on the Onboard Memory, profiles that can contain a whole 'nother set of DPI Steps with whole 'nother set of Macros fitting each game you play, you can save and cycle through 5 different profiles with 5 different DPI Steps on each profile, the limit is you.

7-) The Wheel: Christ, it never felt so good to scroll on something, I can't put it into words beyond telling you that it's extremely solid and premium, it feels big but small at the same time, rubber and Metallic, if you ever grab one of these you will remember what I said about the Scrolling Wheel.

Also in this Mouse they finally introduced a Horizontal Scrolling feature, something that none of my previous mice had.


1-) I don't care what Logitech Calls their new Jumbo Mumbo clicking technology, it is heavy, way too heavy and I think this is because my hands are relatively small and I have to click near where the clicks curve near the DPI Lights using a Fingertip Grip, my Razer Mamba Chroma (A totally crap mouse IMO) at least had something better than this Logitech, the Mamba 2015 could change the Click Actuation Force and the lightest setting was just like I love my clicks, this G900 is way too stiff in comparison, too much for my liking.

2-) The Skates/Feets of the Mouse, my SteelSeries Sensei Wireless had better skates, no way around it. The Skates on this G900 don't glide as much by introducing a higher level of initial friction, this is a hit or miss, you could love this as this should allow you to stop the mouse dead on its place when moving it fast but I don't, I loathe the way the initial friction works and I believe my Sensei Wireless skates are way superior on every way because of this, even more so when I realize that I've used the Sensei Wireless for over 6 months and the skates are still better than this brand new G900.

3-) Its size: Another hit or miss, admittedly I have small hands this, Mouse is uncomfortable for me to use with a Fingertip Grip, I would re buy it again if Logitech Had the mercy of releasing an even lighter but smaller version of the G900, "The G900 Mini" could be a thing smile.gif

If you have large hands ignore this point because this will be comfortable as heaven.

If this mice had better Skates and a customizable click force feature, with customizable size it would definitely earn 5 stars in my review, for this price I expect near perfection quality and features, you were spot on regarding its performance Logitech, but there's room for improvement in other areas, never stop raising the bar.


Pros: Competitive gaming off the wire, customizability

Cons: Price tag you pay for R&D

My sharing thoughts and experience of the Logitech G900 Chaos Spectrum wireless gaming mouse.

At $150 I was hesitant to make this purchase but it was positive feedback from some of our most respected and critical OCN members when it comes to mice which inspired me to give it a try. One thing I've learned in all my years here when these members have good things to say almost across-the-board, you just know this mouse might be a winner.

G900 comes in a quality box one you should keep if you ever want to store or resell down the road. You'll find It's a worthy high caliber, subjectively good looking all around mouse. If you ask me it deserves to be treated well and Logitech did just that presenting it safely to your desk top.

First out of the box I hooked up the cord to the mouse and charged the battery to 100%. The cord, which moonlights as the charger, is very light, flexible and doesn't have kinks. One of the best braided cords I've come across. When charge is complete take off the cord, hook the USB provided to end of cord in place of mouse and your free!

I'm a minimalist and like my mice neat so I removed the two side left buttons and replaced them with solid cover provided. Another two side buttons are provided in case you want to open up the other side buttons to have four side buttons, two on each. One thing I've found that makes this mouse so special, is it's customization.

Logitech software allows you to completely re-arrange button assignments, assign CPI from 200-12000, show battery information, allow firmware updates, use of complete RGB color spectrum along with effects where no LED is an option, all allowing up to six profiles of any combination stored. A profile button underneath the mouse belly lets you scroll through them.

From top to bottom it seems to be a quality build. A tilt hyper-scroll wheel where It's mechanics allows for an on the fly 'free wheel' scroll option. Internal design shows a well thought out placement of premium switches 1 & 2 that lightly actuate crisply down the entire button. Allows for three stored CPI settings where setting is visible from a 3 prong customization LED indicator found just below the scroll wheel lock. All this wrapped in a high quality shell that feels great to the hand wether dry or wet and what seems resistant to fingerprints.

G900 sports a 3366 optical sensor implementation and works well on just about any surface. Logitech reports a 1 millisecond report rate on a 2.4GHz wireless connection and it truly does feel very responsive with a click latency of 3.4 minimum 4.4 average and 5.5 maximum off the wire which is some serious performance under this shell.

I had tried 3 different cloth pads where tracking felt the same only difference was how the mouse weight felt on each pad. I found certain pads that were slower were harder to compensate when targeting dodging objects that was using smaller side to side movements. Smoother glide with good stop will be your best pad IMO.

Feels nice when I palm grip it with my 18cm hand length. On desktop I found the mouse shape comfortable in relaxed palm and slight hybrid claw grip. Gaming I was able to retrain muscle memory and stay in palm grip which felt best to me during intense long periods without any discomfort. At first, I experienced user error accidental clicks of buttons 1 & 2 but with discipline this too got better as I acclimated to using a new mouse.

Shape, size and weight is subjective so take my opinion with a grain of salt. I've found the shape your average ambidextrous size and shape which is nicely done without any crazy contours.

The G900 weight is impressive for a wireless at 107g, no other wireless competes. I found it a bit heavier than I'd prefer when gaming but still a doable weight none the less. I personally feel best when mouse weight is between 80-95g, so this is a compromise for me that comes with wireless and one than I can gladly get accustom in exchange.

Weighing in at 15g the battery takes 2 hours to one full charge that lasts up to 32 hrs without LED and 25 with LED ON and determined by 'real time' mouse activity. When in wireless mode and not in use, this champ goes into a 'sleep mode' that saves on battery power. Logitech reports a capacity of 800 charges.

Note: Removal of battery voids 2yr warranty.

Logitech hit a home run being wireless while competitively responsive and with all of the other specs it offers. It's nice to be free of the cord without much comprises like in the past in order to enjoy. G900 is going to be hard to top when you look at current mice in the market wired or not. Three years of R&D really shines through in creating the chaos spectrum, yet keep in mind nothing is 100% perfect for everyone.

At this price it's hard to recommend, with these specs hard not to. If your lucky there may be a mouse with your exact layout, shape and weight preference for a lot less on a wire. Remember if you don't like the shape, then no mouse no matter how good, is worth it. No one mouse fits everyone's shape, size, and weight preference.

If it's within your budget range and your looking for full flexible mouse and full customization, give this a try. If your specifically looking for a wireless gaming mouse, there is no other I'd recommend. I'm keeping my G900, it easily moves to my main. Good luck finding your next favorite rodent.
