Logitech G502 Proteus Core Review

Logitech G502 Proteus Core Review

The G502 Proteus Core kind of blew my mind.

If you’re anything like me, you don’t really like to cycle through mouses on a weekly or monthly basis. I prefer a mouse that will last me quite some time. For example, I used the Razer Abyssus for close to 5 years before switching to the subject of this review (This is a Logitech G502 Proteus Core Review, if you didn’t know already).

Compared to the relatively non-ergonomic shape of the Abyssus and its relative lack of additional buttons/features, the G502 stands out.Logitech G502 Proteus Core 1 Shrunk

I don’t typically purchase feature-rich gaming mice (I’ve always been satisfied with the mediocrity of most lower-end mice), but I now see what I’ve been missing. While the G502 certainly isn’t without its faults (Which I’ll delve into more below), it’s about as close to perfect as you can hope for.

Fantastic build quality, awesome features and great tracking all combine to make the G502 a pleasant mouse to use for long periods of time. And, let’s face it, that’s what’s really important – How long can you use the mouse before getting cramps?

The majority of us PC gamers probably play games longer than we should, so this is a particularly important factor. 😛

Here’s a brief overview of the G502 mouse before I get into the full review.

Logitech G502 Proteus Core – Product Overview


Logitech G502 Proteus Core 2


  • Very ergonomic and comfortable. This is mostly thanks to the extended thumbrest.
  • Fully customizable with 11 programmable buttons.
  • Awesome DPI settings. You can quickly switch between your custom DPI settings using 2 easy-access buttons, or hold the thumb button down to slow it down to the lowest setting.
  • Tunable weights! I prefer to leave all but one weight out myself, but you are free to tweak them however you’d like.


  • No left-handed version. Sorry, guys!
  • Some people have complained about the metallic scroll wheel, saying its hard to grip. Not an issue for me, but it may be a turn-off for you.
  • No rest for your ring or pinky finger. I would have loved to see the thumb rest mirrored on the right side (With minor adjustments).

Programmable Buttons

Having a few extra buttons is nothing special or unique – Pretty much every modern “Gaming” mouse in existence has at least 3 or 4 programmable buttons. The G502, however, goes above and beyond the call of duty in regards to extra features. It has 11 fully programmable buttons, for starters, though you’ll likely never see a use for most of them.

These buttons (As well as the colors and patterns of the mouse LEDs if you bought the RGB version) are all customizable through Logitech’s Gaming Software suite.Logitech G502 Proteus Core 4

The software is pretty robust and powerful (You can map buttons to web addresses, for one), but I’m pretty satisfied with the default settings. The buttons are all extremely easy to access, and none of them feel cramped. The DPI buttons are located to the left of the LMB, sort of hanging off the side.

You simply tap down on either of them to raise or lower your DPI at will through your custom settings. It’s pretty cool! Additionally, there’s an LED indicator just under these that shows you what setting you’re on.

If you’d rather not have to toggle through multiple DPI settings to snipe someone, have no fear. There’s a button near your thumb that you can simple hold to downshift the DPI to the lowest setting you saved to your profile. This is extremely useful for first person shooters (Particularly Overwatch), but I don’t see much use for it in other games.

Scroll Wheel

Outside of the buttons, the G502 has a few other cool features worth mentioning. First is the scroll wheel – a smooth metal wheel with slight ridges for gripping. The metallic texture of the wheel has been the subject of a bit of frustration for some, as it apparently makes it easy for the wheel to slip out of your grasp.

I don’t know if the people complaining about this rubbed their hands with butter prior to settling down for a gaming session, but I had no problems with this whatsoever. 😀

You can click the button directly below the scroll wheel to send it into “Free wheel” mode. This essentially just allows the scroll wheel to spin without restraint. While I’m sure there’s plenty of you that have an actual use for a feature like this, I just think it’s fun to play with.

The scroll wheel has one more unique feature I want to talk about before we move on. It can be “Leaned” left or right, essentially adding two more buttons to the mouse. The default setting for this is moving left or right on a webpage (When you’re in “Scrolling mode”, where your cursor turns into 4 directional arrows after clicking the mouse wheel in), but I set it to strafing left and right in a few games.

Tunable Weights

Moving on from the rather cool scroll wheel, I want to mention the tunable weights. The mouse comes with a little plastic container housing said weights. The bottom of the mouse comes off entirely (It’s magnetic) to reveal the area for weight placement. The question is, are they actually useful?

To me, no. It’s definitely a cool feature (And being able to adjust the position of each individual weight for optimal balance is nice), but just not one I’ve found much use for.

If this is a big selling point for you, take my opinion with a grain of salt, but I personally don’t notice enough difference to make use of these weights. The default, weight-less mouse is just fine for me! Still, again, the option is there for you if you want to take advantage of it.Logitech G502 Proteus Core

Before I move on to the next section of the review, I want to briefly mention the G502’s surface tuning/optimization features (NOT the weight tuning features).

Using Logitech’s Gaming Software, you can supposedly optimize the mouse’s tracking for whatever surface you’re using and then save that as a setting (Perhaps if you have different desks or surfaces you swap between).

I honestly didn’t notice much of a difference between the default tracking and the “Optimized tracking”, though. This is perhaps not so much a criticism of the tracking software itself, but rather a compliment towards the built-in tracking (It’s awesome).

Materials & Build Quality

If you have experience with other Logitech products (Such as the G710 or the G910 Orion Spark mechanical keyboards), it should come as no surprise to you that the G502 is very sturdy. The rubberized grips and smooth matte materials are fantastic and don’t retain fingerprints much. They feel very high quality, and they’re quite comfortable as well.

In fact, the only part of the mouse that isn’t completely rock-solid is the button directly below the scroll wheel (If you’ll recall, it’s the one that toggles the scroll wheel between regular and “Free wheel” mode). It shakes around a bit in it’s socket, which is a bit troubling.

The G502’s cord is a nice braided material, and the connections (On both ends) feel pretty solid as well. The included weights are also pretty nice – They don’t have any cracks, bends, etc. The bottom plate is attached magnetically to the mouse, though, so this may prove to be an issue later on down the line (If the magnet begins to wear down).

Before I conclude this review, I want to point out something quite important – This mouse only comes as a right-handed version, to my knowledge.

This isn’t an issue for me, but those of you who favor their left hands will be left in the dust this time around. A decent alternative for you might be the Razer Abyssus due to its ambidextrous design, though it lacks the features of the G502.

Final Verdict: 4.5/5 – Great!

Logitech G502 Proteus Core 4

The Logitech G502 is an awesome, comfortable mouse with very few problems to speak of. It’s very customizable in just about every way. There’s plenty of programmable buttons for you to fiddle with, as well as the option to adjust the weight and balance of the mouse. The ergonomic shape and thumbrest also help to make the G502 viable for long gaming sessions.

My only major complaint with the G502 would be that the weight and balance tuning is a bit overhyped – I saw no real use for it, and using weights only seemed to make the mouse feel more clunky.
