Logitech G502 Proteus Core Gaming Mouse Review

mYinsanity was recently supplied with some new hardware from our proud sponsor Logitech G, and now that I've had some time to make use of them, I'll be reviewing the peripherals I've had the pleasure of receiving.

First on the list is the G502 Proteus Core Gaming Mouse. I have been a fan of Logitech mice for quite a few years now, going though models such as the MX 518 Optical Gaming Mouse and the G500 Gaming Mouse, and I can honestly say this is the most comfortable and cleverly designed mouse I’ve ever used. It’s no wonder the G502 has become the world’s best selling gaming mouse, has it’s own subreddit, and was just recently given an upgrade to become the G502 Proteus Spectrum.


First Impressions

At first glance this mouse can seem intimidating with the amount of buttons, the angular design which bucks the trend of a more rounded look, and seemingly endless customization options which we will dive

into later. However, upon resting my hand on this beauty it became apparent there was nothing to fear as it felt extremely natural with every button being easily accessible. The somewhat over sized scroll wheel also caught my attention, with it’s rigid “click-to-click” sensation you hear and feel every movement. Another rather surprising addition was the small rubber thumb rest, as I have never used a mouse which had one. I found myself using it quite often actually, and most of the time it was subconsciously which tells me they really did their research on perfecting the design around the needs and wants of a gamer.



  • The G502 is a relatively smaller, low profile mouse which caters to more of a “claw-grip” style than a “palm-grip” style. I myself having a “claw-grip” found the mouse very comfortable.
  • The scroll wheel has been improved over that of the one found in the G500’s. It feels more prominent and has a more distinct movement to it, as mentioned above.
  • The multitude of buttons are large enough to press without looking for them, yet they are out of the way enough so that they are not accidentally pressed.
  • The thumb rest seems to mostly cater to the “claw-grip” style, as it is in a position that may be awkward or completely unusable for someone with a “palm-grip”. After having to squeeze previous mice constantly while in use, I find my hand still comfortable even after longer gaming sessions.


  • Eleven Programmable buttons
  • Five 3.6g weights that can be added to the underside of the mouse. Unlike the G500’s where there was a removable housing, these diamond shaped weights fit directly into the mouse in various positions. This can give more or less weight to the front, rear, left, or right side of the mouse and creates a truly personal feel.
  • An optical sensor which boasts an adjustable DPI setting which ranges from 200 to an unprecedented 1200 DPI! You can create five different modes and switch on the fly.
  • A testing ability that will examine the surface on which you use the G502, and then optimize the performance. I used this myself on everything from the Logitech G440 Hard Surface mouse pad to a couch arm rest and it’s surprising how well it works.
  • Create Macro’s which can be saved on a per game basis, or as one of three custom profiles.




The Logitech G502 Proteus Core Gaming Mouse is an all-around fantastic peripheral. I found it hard to come up with any negative aspects, with the only one being that it may be considered by some to be too generic and not really aimed at a certain type of game such as FPS, MMO, RTS, etc. so it’s use may be limited at the top levels for each. With a reasonable price point of $79.99 USD, the G502 is perfect for a weekend warrior like myself. I highly recommend you install Logitech’s Gaming Software if you will be purchasing this mouse, as it is streamlined and easy to use when setting up Macro’s, DPI Profiles, Button Mapping, etc and is a must if you are looking to squeeze every last drop out of the G502.
