Logitech G502 Proteus Core Gaming Mouse Review – A Serious Gamer’s Tool

Logitech G502 Proteus Mouse

Let’s face it – most people have heard of Logitech, and most of those who are tech savvy have become well-acquainted with the company’s various offerings over the years. I’ve been mostly pleased with everything I’ve tried from Logitech before, so let’s find out if the G502 Proteus gaming mouse continues the trend.


Some people who use computers regularly do not put much thought into their mouse, but enthusiasts who have a great attention to detail often are very picky with their available options.  Some want a mouse that is rock-solid reliable, giving them years of trouble-free operation for their day-to-day tasks.  Some want a mouse that is fully customizable, with the highest quality construction, and with the most cutting-edge specifications that might just give them that edge they have been looking for to smite an impossible enemy in their favorite online game.

No matter what you are looking for in a mouse, it is my job as your humble reviewer to see if the Logitech G502 Proteus Core tuneable gaming mouse can fit your needs – so let’s have a look!

Logitech has built this mouse from the ground up for the hardcore gaming enthusiast.  You can tune the DPI setting to a whopping 12,000 – which is more than anyone can really use, but hey, it is good marketing if nothing else.

The main left and right buttons are rated for a lifespan of 20 million clicks.  My last mouse died at 19 million clicks, and I was not a happy camper.

On the surface, this mouse resembles something like what you would expect to see an alien who has come to Earth to climb out of.  The front of the mouse has the left and right click buttons that do not run the length of the body, something that I do prefer the look of.  I personally do not like the mice out there that have no distinct lines, almost like a smooth rock, or a halved avocado lying on your desk; I like the sharp-line profile.

The color of the mouse is a matte/eggshell finish dark gray, with a satisfying amount of glossy black trim, giving it a very pleasing contrast.  The only other color on the mouse is the light blue bit where your thumb goes, and of course the lit-up “G”.

The backside of the mouse gives you a feel for how non-left handed this mouse truly is.  If you are a southpaw, you need not apply here.  I personally have what is called a “bear paw” for a hand – large palm area and shorter fingers.  I found that the mouse fit my hand very well.


The mouse comes with a weight system that allows you to add weight to the area of the mouse that suits your preference for center of gravity feel, or make it a little heavier, giving you more precise control.  To access the weight cavity, you simply lift off the door on the bottom of the mouse which is magnetically attached, something that I personally love.  The weights come in a carrying case, so that you can keep them all in one place when you aren’t using them.

Now that we have had a tour of the aesthetics of the Proteus Core G502, let’s have a look at the software.

    The free wheel mode of the mouse is an actual blessing on large vertical documents. I use this mode extensively on another Logitech mouse I own which also features it.

    It doesn’t take long to adapt to the sensitive nature of the wheel, and it allows for very fast vertical scroll. It’s incredible useful if you are a programmer, or even on the web once you get used to it. I agree it is not what you’d expect to see on a gamming mouse. But in a productive environment, it offers a smooth, highly sensitive, precise and fast scroll.

      I agree. I haven’t used a wheel like that since the Logitech Revolution, but I didn’t mind it when I had it, and did like the fact I could scroll up and down a page with unparalleled speed. I’m not sure I’d like it in gaming though.

    It is quite amusing that you cannot find a scenario where the hyper scroll function is of any use. I can give you two:1. Tall web pages 2. Scrolling source code. What is irritating is that you make the assumption on behalf of all would-be users without hesitation. It comes off as very subjective, like saying: “I don’t care for…” or “I prefer….” On behalf of a lot of readers I would like to say that we do not care about your personal preferences :-) Really !
    For me this mouse turned out to be what I was looking for. Not because there aren’t good competitors out there, but exactly because it has that functionality in the scroll wheel(which you can lock to “detent” as you yourself will admit)
    So ultimately this mouse has some of the absolute best features + the feature that you don’t like( But can turn off) Anyone see a problem ??
