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

by Tom Roeder on June 9, 2014 in Peripherals

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.

Page 1 – Introduction

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.
