I love the weights in this mouse, make it feel very sturdy and accurate. Excellent gaming mouse 10/10 would recommend

This is the second one of these mouse that I have had and I simply love it. You can adjust the weight of the mouse to your own liking.

Easy to use and adjust to! The removable weights make a difference, and the locking scroll is really convenient!

This mouse works great. Had no need for the weights but its an added bonus. Feels very good in the hands and very responsive.

This is an incredible, highly customizable gaming mouse. It goes above and beyond what I ever expected of it.

I was really excited to see this mouse go on sale. The G502 Proteus Core comes with several programmable buttons that are helpful for not only gaming but productivity as well. I use my desktop for both and this mouse complements my setup greatly. The reason I stuck with this mouse over other mice I've compared it to is the infinite scroll wheel. Logitech has such an amazing feature in the scroll wheel. I've been using Logitech for many years, I know to always look to their products first before anything else.

The buttons feel great and it fits great in the hand and comfortable. I love the customization and color led.

I bought my first G502 about 5 years ago and recently purchased a new laptop so I needed a second mouse. I thought "Hey if it ain't broke don't fix it" and immediately purchased the new Spectrum G502 model. 5+ years of using this mouse and I've never had a problem with it. I think it has a better design than most other mouses but that's personal preference. If something was to ever happen where I would need a new mouse, I wouldn't think twice before picking up a new G502.

Upgraded to this mouse from a Corsair and I’m very happy. Big enough to fit my XL hands and has great DPI settings.

Good, comfortable mouse. Easy motion. Quick setup with the Logitech software. Multiple positions for the weights so it can easily balanced. Only complaint is I keep hitting the thumb button by accident. This is the DPI shift button, so it doesn't do anything unless you hit the DPI up or down buttons too, but it occasionally gets in the way. Overall, a great mouse.

I rarely play game but I used this mouse only for work. Man I loved it. It just fits right and so comfortable. 5 star

I am a gamer as well as a designer and I used to use the Performance MX Logitech mouse but got tired of the always dying battery. So when it came time to buy a mouse I looked up other reviews on this one. Only downside I saw was that it was a corded mouse. I will probably never go back to a wireless mouse again. The cord is long and thick and tough. The features on this mouse both for gamin and when I use it for design really make it effective for both tasks. I can not say enough about this thing.

I bought this mouse because a lot of pro gamers use it, and it’s affordable. Best mouse you can get for the price

Everything you could want in a mouse. The buttons are incredibly well placed for reflexive, minimal effort activation with satisfying response. Nothing feels cheaply made or overly sensitive. The adjustable weights in the base may seem unnecessary or like overkill, but after a few minutes playing around you'll wonder why it isn't an industry standard feature. And for anyone wondering about the support software, it is very intuitive and easy to set up. Highly recommend this prouduct. Your search is over

Well built and functional gaming mouse. Being able to adjust the weight of this mouse makes it one of the best.

There is a button that locks the scrool wrheel, between click mode and a very fast one, sometimes it would scroll when base moved untill I learned the first button next to wheel changes it's behavior, but is a good size and comfortable

overall a good product just wasn't impressed - looking for a different one

I love this product, I really recommended you really get what you paid for

Works well for gaming and looks pretty cool. Logitech makes good products.

Haven't had the mouse long and still getting used to it. It's very comfortable to hold and fits the hand well.
