G900 CHAOS SPECTRUM
PROFESSIONAL-GRADE WIRED/WIRELESS GAMING MOUSE

FEATURES

G900 CHAOS SPECTRUM
PROFESSIONAL-GRADE PERFORMANCE

Trusted by top eSports athletes
In high-pressure moments, latency can be the difference between winning it all or losing. With millions on the line, top eSports professionals can depend on G900 Chaos Spectrum. Featuring a 1-millisecond report rate and our highly optimized 2.4GHz wireless connection, Chaos Spectrum delivers incredible responsiveness for competition-level twitch targeting.


G900 CHAOS SPECTRUM
OUR MOST ACCURATE OPTICAL SENSOR

Pixel-precise performance
Chaos Spectrum comes equipped with the PMW3366 optical sensor — widely regarded as the best gaming mouse sensor on the market. PMW3366 has zero smoothing, filtering or acceleration across the entire DPI range (200-12,000DPI), delivering exceptional tracking accuracy and consistent responsiveness at any speed. For even better accuracy and speed, use surface tuning in Logitech Gaming Software to tune the sensor to your playing surface.


G900 CHAOS SPECTRUM
LIGHTWEIGHT CONSTRUCTION

Superior comfort and speed
Every component of Chaos Spectrum has been optimized to reduce weight while maintaining stability. Each element of the construction was analyzed and adjusted to remove milligrams wherever possible, from thin wall molding to a hollow "spoked" hyperscroll wheel design. The result is a wireless mouse that weighs in at only 107g, maximizing comfort over extended periods of use and delivering quicker response to motion.


G900 CHAOS SPECTRUM
AMBIDEXTROUS DESIGN

Customizable to fit your hand and style
Fully-configurable button layout and ambidextrous design allow for left- or right-handed use that works with nearly any mouse grip style, including palm, claw and fingertip grips.


G900 CHAOS SPECTRUM
POWER EFFICIENT TECHNOLOGY

For high-endurance gameplay
Chaos Spectrum features exclusive clock-tuning technology that significantly reduces power consumption, so you can play for a continuous 32 hours — an entire competition weekend — on a single charge.* Battery Assistant in Logitech Gaming Software keeps you informed about your charge level and gives you an estimate of your remaining battery life.

*Battery life up to 32 hours with lighting off, or 24 hours with default lighting.


G900 CHAOS SPECTRUM
EXCLUSIVE CLOCK-TUNING TECHNOLOGY

Faster and more reliable
Chaos Spectrum clock-tuning technology maximizes speed and battery life while minimizing degradation commonly caused by temperature, humidity, aging and part-to-part variances.


G900 CHAOS SPECTRUM
MECHANICAL PIVOT BUTTON DESIGN

Fast, accurate and reliable click performance
A metal spring tensioning system and metal pivot hinges are built into left and right mouse buttons for a crisp, clean click feel with rapid click feedback. This system helps reduce the pre-travel distance between buttons and switches while also reducing the force required to click — enabling faster recovery after each click. In addition, this system helps ensure a lower, more consistent and predictable click force from click to click.


G900 CHAOS SPECTRUM
11 PROGRAMMABLE BUTTONS

Control at your fingertips
Use Logitech Gaming Software to program your favorite commands and macros to each of the up to 11 buttons.


G900 CHAOS SPECTRUM
PROGRAMMABLE RGB LIGHTING

Choose from 16.8 million colors
Chaos Spectrum features two lighting zones that can be customized independently to match your style, system or environment. With Logitech Gaming Software, you can select from a spectrum of up to 16.8 million colors and synchronize lighting patterns and effects with other Logitech G devices.


G900 CHAOS SPECTRUM
WIRED AND WIRELESS

Best of both worlds
Plug in the data and charging cable to seamlessly switch between wireless and wired modes without interrupting your game.

What I expected.

Pros: - Wireless and Wired smooth transition that does not require any user interaction
- Great precision
- Ergonomics
- Software for configuring and options it offers

Cons: - Plastic gets a bit worn on sides over time (its noticeable after few months, as with all Logitech mice)
- Price (then again, quality costs)

Other Thoughts: I finally decided to move from my MX518 since my Chinese supplier finally run out of them (when something works good I dont change it regardless of how much OEM brags about its new equipment), and I was a bit put off since a lot of people complain about mouse acceleration and other nitpicks, abut I am pleasantly surprised that this mouse behaves exactly as my good ol MX518, regardless of it being wired or wireless. Also unlike my MX518 this one works good on desk as well as on cloth pad.

Potential to be amazing, ultimately falls short.

Pros: Buttons feel solid, ambidextrous without sacrificing comfort in either hand, tracking is amazing.

Cons: Battery life is a blatant lie on the box. If you disable the onboard lighting the mouse onboard lights turn on and stay on during sleep/standby or off situations running the battery down uselessly. Despite many requests for months in the logitech forums this issue has not been addressed. The basic design of the mouse will inherently make periodic cleaning difficult as there is a huge surface area of places for debris to collect. This is a hygienic issue that should be noted. The charging cable is a microb, the included cable have some wings that prevent it's use on other microb devices. (I just cut my wings off with a razor blade however it's a truely strange modification to an otherwise industry standard interconnect) I believe the hardware is excellent and if Logitech could just fix the lighting issues I'd be willing to throw it a few extra eggs. As it sits right now (2017/09/10) this is an unfinished product with the highest price tag around.

Other Thoughts: I came from the Logitech Performance MX mouse which had an inherent middle click failure. Logitech warranty did replace 2 of them over 3 years however they don't seem to address issues with their products after release. I unfortunately have to recommend something else at this time.

Logitech G900 Chaos Spectrum Professional Grade Wired/Wireless Gaming Mouse

Pros: - Great performance!
- Ergonomically friendly.
- Battery life is amazing.
- Aesthetically pleasing.
- Wireless is on par if not better than the wire connection.( I prefer wireless over wired in games and productivity 9 times out of 10)
- Shipping and packing was well done.

Cons: Nothing that I have encountered as of yet.

Other Thoughts: I would recommend this mouse to anyone. This has been the best feeling and functioning wireless mouse that I have used. If you want a mouse that makes you feel in control this is the mouse for you.

Thumb buttons don't work in wireless mode. Really expensive.

Pros: + Good ergonomics.
+ Best mouse sensor on the market
+ Excellent battery life.
+ Decent ergonomics
+ Ambidextrous
+ Good mouse wheel
+ Sturdy cable and connector, looks like it'll be quite durable
+ Not too heavy, not too light.
+ The RGB is actually useful, as I currently use it to display different colours for each profile. Blue for General / Browsing, Green for Production, Red for Gaming

Cons: - The thumb buttons don't work in wireless mode. This is a common problem that has not been addressed by Logitech. Updating firmware has not resolved the issue.
- It's EXPENSIVE
- When doing the middle click, it has a tendency to scroll left (tilt the mouse wheel left) at the same time. I upgraded from a G700 where the tilt left / right worked perfectly and so I'm used to having the mouse wheel tilt left / right bound to "forward" and "back" on my web browser and middle click for "close window". Unfortunately this problem makes the wheel left/right tilt much less convenient to use in browsing, and completely useless for gaming.

Other Thoughts: - Due to the issues I would *NOT* recommend this mouse at this point because for the price you're paying you expect everything to work perfectly out of the box, and the non-working thumb buttons in wireless mode is a dealbreaker for me. I might have a dud unit, but it seems to be a common problem on the Logitech message board.

Final score: 3/5. -1 egg for non working side buttons, -1 egg for middle click / scroll left problem.

not bad

Pros: Overall a great wireless mouse. But I'm surprised no one mentioned that you cannot remap thee left and right mouse buttons or do scripting on those buttons. For a gaming mouse this is pretty limited considering the $50 Logitechs have this option.

Cons: What I said above

One of the best Wireless Gaming Mouse on the market

Pros: -Mechanical Pivot Switch to reduce pre-travel distance
-Amazing DPI Light and Logo RGB effects
-Hyperfast Scrollwheel
-You can save up to 5 profiles
-11 Programmable Buttons (fully customizable via Logitech Gaming Software)
-Ambidextrous buttons and it's fully modular, whether you're right handed/left-handed
-Weighs about 107G
-Can last 24Hour battery life with RGB Lights/ 32Hours without RGB Lights, regardless polling rate, usage hours, and brightness/color cycle rate.
-You can switch between wired or wireless mode via USB braided cable adapter
-2.4Ghz USB Dongle

Cons: -Does not come with tuning weights
-Shape may feel slightly narrow but symmetrical feel which is engineered to support ambidextrous control
-High arch buttons is little too high and I wish it's a little bit lower to tap buttons faster
-It would've been nice to have G-Shift of DPI Default Button on left side button for right handed user
-Does not come with charging dock

Other Thoughts: Wireless click latency and motion latency was very good. In the past, wireless mouse suffers battery, latency, and the weight issue. DPI up/down shift buttons should be above tactile hyperfast scroll wheel button to easily press DPI shift buttons. That way it'll be a lot easier to improve muscle memory. I come from G502 Proteus Core, and it's by far one of the best wireless gaming mouse on the market! If shape and ergonomic is your biggest concern, you can go with simplistic wireless mouse which is Logitech G403 which is optimally designed for right-handed user only. Overall, I love this mouse a lot! In the near future, I'd love to see wireless version of Logitech G502 Proteus.

Amazing mouse. Great quality build, even better accuracy across the board.

Pros: Awesome sensor, wicked response time and cable free!
The best wireless mouse there is.
24 h battery life, very easy to keep charged!

Cons: Sorta expensive.
you do gotta charge it.

Other Thoughts: If you are on the fence, it is worth it. Highly recommend it, always dealt with cable drag in the past and finally decided to go the wireless route when this thing came out. I have never looked back since!

Great mouse but may not be worth the price

Pros: -Wireless works flawlessly with a good battery life
-RGB lighting and being able to sync with my other Logitech devices
-Buttons feel great
-Unlike other mice that have sensativity adjustments on the mouse these are hard to accidentally hit

Cons: -Odd overall feel. Takes some getting used to
-I ordered a G240 mouse pad with it and the software has a setting specifically for a Logitech cloth mouse pad. While that would seem like a pro, the mouse works better on factory default.

Other Thoughts: While this is undeniably a great mouse I would only recommend it at the $149 price point if you really need a wireless mouse or just have money to blow on a cool toy.
