This is the absolute best corded mouse that I have ever used to date! I'm not a professional gamer, and the possible 1 millisecond drag that might result from the cord doesn't bother me. I have owned the previous version of this mouse (the G502 Proteus Core) and it has performed perfectly for more than six years. I'm more than sure that this improved version of the G502 Proteus Core will last me at least as long as the original model, and I very highly recommend this mouse to everyone, gamer or not. Side note: two of my siblings have purchased this mouse because of my recommendation, and they both said that this is the best mouse that they have owned to date.


Liked by users, great price


- Comfortable thumb rest - Textured plastic providing awesome grip (no grip tape needed for this mouse at all) - Works for both claw and palm grips - Optical mouse switches giving quick rebound on the left/right mouse clicks without the spongey feeling other mouses tend to have on them - Side forward and back buttons are easily reached - Free spin center wheel, or clicking, or hybrid options for scrolling

Amazing lighting and key response

-Its a desk pad -Looks decent

Much Better tactile feedback than the original 502, which was already great. The new buttons are much easier to "fumble-find". The original model sacrificed some usability for sexiness.

I just got this and set it up and it feels sooooo good. It looks good, nice and quiet and the fact that you can use it with or without the cord a real plus. Out of all the gaming keyboards I have owned over the years this has been the most expensive but easily worth it. Super easy to set up and use.

Great functionality. Light keystrokes, minimal noise...

Quiet key strokes, RGB lightning

high battery life good size good weight very responsive no noticeable input lag

- Easy to see in the dark. - Comes with a mouse so you don't have to hunt for one. - Isn't Tenkeyless, meaning more functionality. - Makes those beautiful clacks that I love. <3

like a razer naga but more affordable. fits big hand OK, not great but OK. lots of buttons

Solid mouse. Easy to use the buttons and the arm/wrist position is much better.

Ive owned the keyboard model before this one for many years and this model for at least a year before I bought this second one for my Dad. For the price its great, and the past models of Logitech products have lasted me many years and lots of use. This keyboard is big enought to type on , but not so big that you wont mind carying it. And little weight. The range works fine in the same room, and can even go into an adjacent room close to a doorway and it still works.

Has the right shape for my hand and grip. Optical switches. Higher quality stiffness in the plastic casting. Very good Scroll Wheel Electromechanical lock on the free wheel for scroll wheel so it will work for millions of cycles!

*Feels solid *Action is smooth but crisp *Very responsive *Value seems to match the price *Packaged nicely
