Customer Ratings & Reviews

The Chaos is the best mouse I've owned to date. Hands-down. It's sleek, smooth, solid and reliable to a point approaching perfection. The sensor technology is suberb, the software integration is flawless and wireless battery life is hard to believe, especially considering it's Spectrum and actively synced with my other devices. The button configuration is unique to the many mice I've owned as it is possible to place two buttons on the left (rh), two on the right (lh) or even two on both sides. The last option was tempting due to the quantity of buttons available for various games, but in practice caused too many inadvertent presses on the right side. Maybe it's possible to get used to it or maybe some people have hands that may accommodate the layout, but mine do not. For the record, while it's an option to have four buttons, I doubt it was the intended function, at least for hardcore gamers. So it's tough to knock it for something it doesn't pull off perfectly when it's an add-on. That leads me into my only complaint about the mouse. The reason the extra buttons didn't work for me is because the mouse is slightly too small. My second favorite mouse ever is the Deathadder Elite. Where it fails in comparison to the Chaos, it's best feature is the size and shape of its body. If the Chaos was about .5 inches wider, it would be the perfect mouse. Not enough to take a star off, because it's probably perfect for many out there, and it's not enough to cause any problems in any games. It's just not 'perfect.' Other than that one problem, it's the best mouse on the market today. Period.

While I agree the price is a little steep, none the less its a great mouse. You have the option to go wireless or wired and to be honest I can't even tell the difference between the two. I do, do some gaming and still there is no lag (that I have noticed). The mouse is packaged nicely and its extra accessories come in a nice small storage box. Overall great mouse and battery life that offers you the option to go wireless or wired.

Light, perfectly accurate, and a batter that lasts for days. After much research I am extremely happy I decided to purchase this mouse. It runs circles around my old Razer Ouroboros. The wireless is second to none and the fact I can use it, even with intense nights of gaming, for a couple days is just amazing.

best mouse ive used by far. excellent design and comfort with great customization and no lag. worth the price would reccommend .

Did my research about various gaming mice for weeks and initially felt ambivalent about purchasing this product because of price and instead purchased a lower price point mouse with a similar quality sensor. When a sale arrived, I jumped on this purchase and do not regret it especially coming from my previous heavy weighted mouse purchase that caused me a great ordeal of wrist/arm strain (despite setting dpi setting to really high). This mice is absolutely much lighter (previous mouse was ~135g), sensor is top of the line, and can definitely feel the difference in sensor (when I was playing CSGO) despite quality is literally only a minor few levels above. I like the various buttons it has as I can for example adjust dpi on the mouse without needing to load the software application and rotate back and forth on pages without needing to drag my mouse to the top left to manually select "back one page" or "forward one page". The scroll wheel on this mice is a plus too. The response and movement is very quick and there is a button to enable/disable scroll wheel physically from sliding super fast from middle finger touch (very useful as I like fast wheel scrolling for browsing/scanning through webpages quickly and locked/slow wheel scrolling for video gaming so I don't pull out something I don't need it by mistake when playing games like CSGO). Overall, I'd definitely recommend this mice If you are looking to have a more comfortable gaming experience (I play casually) or to ease surfing.

One if the best wireless mice I've ever used, no lag at all. Comfortable, long use time between charges and easy to make hotkeys.

Logitech gaming mouse performs beyond expectation. Accurate, quick, and NO CORD, with long lasting charge! Wireless gaming mouse!

This a great mouse, not too big, not too small. Fits perfectly on my small hands. There is no lag at all, and you can use it either plugged in or wireless. You can turn off the RGB effects for better battery life. I loved the positions of the side buttons, they can be changed to the other side, if you are a lefty. I got the mouse half price on a recent sale, however it is well worth the price even at a regular price. Before I had a Corsair rgb mouse and I didn't like the size at all. Oh, by the way, this one has infinite scroll if you like to activate it, and you can customize profiles per game if you want too. Best wireless gaming mouse I had!!!!

I upgraded from the G502 mouse and am loving the G900. Compared to the G502, it's lighter so that can be a pro or a con depending on who you are. Personally for me, it's a pro as the mouse feels like it just glides smoothly when I move it. Ergonomically speaking, everyone's hand is different, but for me The G900 feels good in the hand as a rightie. Clicking with the mouse feels immensely satisfying. I'm not sure how to explain it other than the audible click and the tactile response feeling just right. I like how you can use the mouse wirelessly or wired. The response rate is really good when it's wired, feels the same as wired for me. You can change the DPI on the fly and it's stored on memory. Using Logitech software, you can also change the color on the mouse's logo or turn it off to conserve battery life (around 30 hours). The mouse will automatically turn off after a period of inactivity though it wakes up from sleep fast. The only con is that it has one less button than the G502(on the side). Nevertheless, I can live with that. Even if you're not a gamer, I still highly recommend this mouse, especially when you can proudly proclaim, "I use the Chaos Spectrum!"

I've been a fan of Logitech G series for 10 or so years. I've always been happy with their quality. The G900 falls right in place. The main features of the mouse are the ambidextrous configuration you can set and the battery life. It's also super lightweight versus other gaming mice I've used in the past. The charging cable included with the mouse is braided so even while charging there is little to no obstruction of movement. Highly recommended.

Combines the best of a wired and wireless mouse. Great product, responsive, comfortable and looks cool!

I use mouse more than 10 hours daily for my job and entertainment. Especially after 8 hours of work, I had pain in my finger and wrist. I got this mouse on BF for half price. I was amazed in that this is the lightest quality mouse and with unbelievably customizable buttons. Also, light weight fast scroll wheel, too not to mention the longer battery (last more than 2 days for heavy daily use of 10 hours or more). If you use mouse more than 8 or even 10 hours daily and have some pain in the wrist or finger, then get this at all cost ($150 is some expensive for a mouse, so if you can wait then look for holiday sale like me) Even for $150, it is worth every penny.

The price may seem steep, but after using it for about a week I've seen this as the best mouse I've ever used. The battery time is about 26 hours with a really short charge time. You can choose the side the buttons are on the mouse so it works for both left hand users and right hand users.

I bought this mouse to replace a Logitech G502 (which I love) but is only wired. I halfway expected to return this G900 because I loved my G502 so much, and just deal with it only being wired, but as soon as I plugged in the G900, I fell in love. It feels great in my hand, has up to 11 buttons (like the G502) and of course, can be wireless. It exceeded my expectations and I was fortunate to get it for only 79.99

I chose this mouse because it both wired and wireless. I also wanted a new gaming mouse since my last one was starting to become unusable. So far I really like this mouse a lot. It has rechargable batteries built in so no replacing them. You can connect it, let it charge and still use the mouse which I love. The battery so far lasts a pretty decent amount of time with moderate usage so you more then likely won't have to charge it every day. The mouse is very responsive. Fast and accurate. It is a good weight, it's not too heavy but heavy enough in my personal opinion. The buttons are nice. Feels sturdy. Another nice thing about this mouse is that it's for both right and left handed people which for gaming people seems to be a of a problem if you want a gaming mouse from what I have heard from others. The one thing I wish was a bit different is that the scroll was not quiet as stiff but that is not a big thing or going to cost it a star for me.

this mouse is a super do it all mouse. I can change my music, go back/forward on webpages, and change the volume all on the mouse. the programmable buttons are great. as a gaming mouse it is smooth and there is no lag on wireless. the high dpi allows me to turn and aim quickly. it is a night and day different with a regular mouse that comes bundled with a computer. worth the purchase price.

Zero latency or lag. Works wonderfully on any surface with surface calibration via Logitech software. Battery is pretty good, and you can tweak it to last longer, I think up to 32 some hours of use with the rgb light off. Hands down the best mouse I have ever used. If I can one con, it would be that it is also the lightest mouse I have ever used, but just takes some getting used to.

I'm aware that there is a newer model of this mouse but i got a steal on this one. If you aren't looking for wireless charging and the addition of a 10 gram weight, then get this one over the G903. In the future when this one has done its time ill transition to it. The mouse has an Ambi shape to it and fits my relatively large hand well. I've been using it to play mainly FPS and for general PC use, its impossible to tell that its wireless until you've realized that your not snagging wires or have increased drag because of it! Sensor is way more responsive than any average human can appreciate and the switches' used on all the buttons are excellent... did i mention the amazing scroll wheel. I was originally using the G-Pro but it was too small and giving my hand cramps.

I was looking for a gaming mouse that can be wireless and lasts a good while on battery. This mice is comfortable for my hands and overall perfect other than the price in my opinion. Ultimately I purchased it only when this went on sale.

One of the most comfortable mouse I have ever used. I have a problem with the side buttons working the first few times pressed but overall impressed with performance.
