Review: The new Logitech G502 Proteus Core is the greatest

Last Updated July 29th, 2021

It’s tough for me to say exactly how many different computer mice I’ve used in my life. I’ve been using computers in some fashion since 1990, and it’s easy for me to count up more than 20, and that isn’t including all the ones I’ve run across in classrooms or places I’ve worked.

I’ve used plenty of traditional mice, wired and wireless, optical, laser, and even the old-fashioned physical ball (remember how you used to have to take those out and clean them every once in a while? Our grandchildren will think we’re making that up). I’ve used my fair share of gaming mice — most recently the Razer Mamba — to play shooters, MOBAs, and other types of games requiring the responsiveness and performance of a gaming mouse.

This is all a long-winded way of saying that I know mice.

The Logitech G502 Proteus Core is the first mouse I have ever used that has made me say “Wow.”

This official video from Logitech runs down some of the highlights:

Look, feel, and performance

As soon as I put my hand on the G502, I knew it was special. I’d never before used a mouse that seemed so perfectly designed for the way my hand naturally rests. A generous inward on the thumb side provides a natural resting place for your thumb, and the rest of the mouse fit perfectly in my larger-than-average hand. The materials used in the construction of the G502 — a combination of high-quality plastic and metal accents — are smooth and comfortable, even after hours of intense gaming.

I tested this mouse while playing TitanfallDota 2, Frozen Endzone, and Age of Wonders III, and I never experienced a moment of anything other than perfect comfort. The sides of the mouse are pleasantly textured for grip without being rough, while the top surfaces are smooth and comfortable on the palm. I highly recommend you try out the mouse for yourself if you get a chance, since different mouse grips can change your experience with a given mouse, but the 3D look at the mouse available on the Logitech web site does a great job of giving you an idea of the device’s construction.

Aside from a great hand-feel, the G502 Proteus Core also looks great on your desk. The combination of colors, materials, and angles seems pleasantly futuristic. The glow of the LED “G” on the mouse body is bright without being overpowering, and perfectly matches the blue accent on the thumb-rest. The ability to change the color or brightness of the LED would have been nice, as always, but that’s a tiny complaint considering the overall quality of the mouse. From the quality braided cord to the smooth underbelly, the device was practically perfect.

Regarding performance, in my two weeks of testing with the G502 I never once had a complaint. The mouse features on-the-fly DPI adjustment between up to five profiles that you can tweak yourself using Logitech’s software, and those profiles can be set anywhere from 200 to 12,000 DPI, an enormous range that should be enough to satisfy just about everyone. The mouse also features Logitech’s “Delta Zero” technology, which is a fancy way of saying it works well variety of different surfaces. I spent hours and hours playing a variety of games with the G502 on mousepads and several desks of different textures, and I never experienced a single incident in which the mouse let me down.

The extras

The G502 Proteus Core is more than just a great-feeling, great-looking, great-performing mouse. It comes complete with a few special features that are enough to push it over the top from “good” to “outstanding.”

For the hardcore gamers or the especially-picky out there, the biggest asset of the G502 is its customizable weight. The belly of the beast opens up to allow you to insert as many of the included weights as you like, in whatever configuration is necessary to get the mouse to feel just right.

Personally, mouse weight has never been a big deal for me. I never felt the need to add the included weights, though I appreciated the fact that they were there if I ever felt that I needed them.

The scroll wheel of the Proteus Core was of much more interest to me, and will be one of the first things I mention to people in the future when I’m recommending that everyone pick up this mouse. That’s because the scroll wheel of the G502 is covered in metal, rather than plastic, and it feels fantastic. The metal stays cool to the touch no matter how long you use the mouse, which I love, and feels much more solid and substantial than typical wheels. Clicking with the wheel took a bit of getting used to, since it required slightly more pressure than usual, but the solidity and resilience was a fantastic feature, rather than a drawback.

The scroll wheel also features the ability to scroll freely at the press of a button, a fantastic feature that has been present in Logitech mice before. With previous mice, I’ve always found the scroll wheel to be something that either works or doesn’t — the G502 Proteus Core features the first wheel I’ve ever thought was a major selling point for the mouse.

My View

Here are the criteria I consider most important for judging the G502 Proteus Core:

#1 Feel — 10/10

The thumb rest, the metal scroll wheel, the size…just flawless in every way.

#2 Appearance — 9/10

It’s not a work of art, but it’s just about as close as a gaming mouse is going to get.

#3 Performance — 10/10

I didn’t have a single complaint in all of the hours I spent using the G502.

#4 Extras — 9/10

The customizable weight is the big plus here. A wireless mode or the ability to change the color of the LED would have been perfect, if I were bold enough to ask for the literal mouse of my dreams.

Overall score: 9.5

The Logitech G502 Proetus Core is the greatest mouse I have ever used, and I’ve missed it every day since my time with it was done. You can pre-order it now. It will be released later in April.
