Customer Ratings & Reviews

This mouse is perfect. I love the feel of it, the adjustable weight, and the settings it has. Definitely the best gaming mouse I've had.

The weighted system it uses helps a lot with the aiming. The buttons are useful for games with a lot of equipment.

I use this mouse on a daily basis in my home office. I love the way my hand fits around it and all the buttons and wheels are easily worked. It moves easily on my mouse pad, but also works well on my glass desk.

I bought this mouse from Best Buy as an impulse to replace my gaming mouse and it has made a significant difference. I have seen my gaming improve the mouse is more ergonomic and suited for my hand playing FPS's.

Super comfy in my hand, looks great, and love adding and removing the extra weight as desired. It works flawlessly and perfectly.

Very confusing how the G502 has two different skus, one with a blue light and one with an RGB light. The blue light one regularly goes on sale but the new RGB one drives up the price. You'll never even see the light since it's under your hand. The mouse is fine, but don't buy this one, buy the other G502 mouse with the blue light because it's way cheaper and literally the same mouse.

Really great mouse for gaming. Very responsive and the weights help a lot. Highly recommended to any pc gamer.

Pros - Best sensor on market - Great Price - Great Feel Cons - Heavy - Must like blue because theres a lot of it

The free wheeling scroll is the best thing I've found for 3d CAD environments like solidworks. I prefer this over a 3d mouse and have become a big fan of this logitech model.

The mouse looks and feels fantastic. Things to note are that its only for right hand use and the color of the light that comes out cannot be changed. If you can look past those its a great buy when on sale.

I actually spent a few days before choosing this mouse and I'm really glad I bought it. It fits perfectly in my palm and my fingers can easily reach the programmable buttons.

This is really a great mouse for the serious gamer. Having 3 easy to reach and use buttons for the index finger is a huge advantage for games that require a lot of binds. The quality of the build is what you'd expect for Logitech. They're mice are really second to none and this one is probably their finest moment.

Great laser mouse very good for fps game and mmo. good look rgb on the mouse. Has nice low and high Dpi setting.

I bought the Proteus Spectrum to replace the original Proteus Core that I absolutely wore out from use. Sadly I was well past the 3-year warranty period on the Core model and the Spectrum is everything I liked about the original only better. Of course buying the Spectrum was an easy decision. The best thing about this mouse is how comfortable it is no matter if you are gaming for hours or just doing mundane things like web surfing, reading emails, or work related things.

Best features: 1. Calibrate to any surface 2. Sniper Button allows for different DPI setting to lock when pressed. 3. Logitech G Software excellent. 4. Perfect number of buttons for FPS games. 5. Weight system perfect customization.

Works good is very comfortable does what it's suppose to like the weights included they make it feel more substantial

I originally bought the Corsair M65 and the sniper button was awesome but it was smooth and sat directly under my thumb so when I'd lift to move the mouse I would slip on that button. Aside from that one little detail it was great so I went back to looking and wound up with this. This mouse is a bit longer and a hair more narrow than the Corsair with a wider thumb platform. So depending on how you hold the mouse one of those two is ideal for you. Personally Logitech is the best in my book.

A great mouse and offers a ton of customization, and being able to adjust DPI on the fly, even mid-game is an amazing feature.

Plenty of buttons and very configurable for any gaming need. The wheel is very precise when locked into incremental turning too. My last mouse had the same optional free spinning wheel and it slipped and/or failed to register a turn so this is nice. I like my mouse as light as possible but there are plenty of weights to add to it if you need more heft. I can't speak to the durability of it but Logitech has overall been very good to me and it looks pretty nice glowing in sync with my Logitech keyboard.

I really liked the adjustable weight setting, allows you to personalize your gaming. Has great sensitivity and button placing is perfect.
