Logitech G502 Proteus Core Gaming Mouse Review

There is nothing more frustrating (or deadly) than having your equipment fail you during a life or death situation on a Battlefield, virtual or otherwise.

While they probably can’t help you much with the “otherwise”, Logitech is hoping the replacement their flagship wired mouse can see you through any hardships you face virtually.

Lets see if a spiffy new look, revamped wight tuning system, and an extremely accurate sensor can deliver on that.


While the most obvious change from the G500/s line is the G502’s angular design, the most substantive change is the sensor. The Proteus Core, which Logitech claims is the most accurate sensor on the market, sports a DPI range from 200 to the somewhat ridiculous 12,000. If you’re just planning to surf the web and play you’re occasional FPS on a single 1080p monitor, the 12K DPI will mostly be wasted on you. However, it may come in handy if you ever find yourself with access to a bank of 4K monitors.

As far as ergonomics go, the G502 has a lower profile than its wireless cousins the G700s and G602. While I prefer the the grip I get with my trusty G700s, the G502 feels great in the hand and all of the mouse’s 11 programmable buttons are all easily accessible without being easy to mistakenly hit.

The G502 features Logitech’s patented scroll wheel that can be used in the standard click-to-click mode or in a frictionless mode similar to a trackball. The G502 does improve on the design of the G500 a bit by moving the button to change the scroll tension from the bottom of the mouse to directly behind the scroll-wheel, making it only a quick move of the index finger away. Another notable change is switching from the magazine style wight system that put all of the weight in one place to a design that allows you to modify the center of gravity of the mouse.

A big part of the reason the G502 feels better in the hand than its predecessor is the surface materials Logitech chose. Using matte paint for the majority of the palm and left and right-click kept me from getting the slippery feeling you occasionally get with glossy plastic mice. The textured rubber on either side of the mouse was also a nice touch. The only complaint I have is this area would have to be the faux metal scroll wheel. While getting purchase during normal scrolling wasn’t a problem, using the right-click on the scroll wheel with any consistency was almost impossible.


As with all of Logitech’s modern gaming peripherals, the G502 can be customized using the easy to use Logitech Gaming Software.

Any of the mouse’s 11 buttons can be reprogrammed. The G502 can store up to three profile on the mouse itself, or a seemingly unlimited number of profiles on a computer. Logitech Gaming Software also has a neat feature that auto detects when you are playing a game you have a profile for and automatically switches to it.

The most innovative feature of the G502 is the ability to use Logitech’s software to calibrate the mouse to the specific surface you will be using it on. The mouse come with the standard factory preset as well as presets for Logitech’s cloth and hard gaming surfaces. Calibrating is easy as placing the mouse on your surface of choice and moving it in a figure eight pattern for a few seconds.

The G502 also features an illuminated G on the palm of the mouse that can been seen while in use. It’s a neat idea in theory, but I found the bright blue to be a bit distracting. It would have been nice if Logitech allowed you to dim the light to something a more tolerable. You also can’t change the color of the light from Logitech’s signature G series blue. That’s a bit of a bummer.


The mouse is as responsive as you would expect a gaming mouse to be. There is no noticeable acceleration. The macro buttons are all well placed. The lift off distance is minuscule, though there is a bit of movement when placing the mouse back down.

While all of those things are good, they’re fairly typical. The best part about testing the G502 for me had to be experimenting with the five 3.6g weights included with the mouse. I honestly didn’t expect to adjust the weight as much as I did. Apparently, I prefer a heavy mouse while playing FPS ( I like to snipe) and a lighter mouse while editing video or browsing the web.


Logitech took the nearly perfect G500s and spiced it up with the only programmable sensor on the market, a new look, and a well thought out weight adjustment system. At the very competitive 79.99, the G502 is one of the best mice out there for the gamer looking for a high-end wired gaming mouse.
