Notice: The Logitech G502 Proteus Spectrum is not available in most stores now because there is an even better model now. Scroll down to “The Logitech G502 Proteus Spectrum VS the G502 Hero” for more information.

Today we’re going to be having a look at the Logitech G502 Proteus Spectrum, which is a gaming mouse designed to not only satisfy your RGB needs, but to also take your PC gaming to the next level!

Although that’s what it was designed for, does it really own up to all these standards? Well that’s why I’m here to give you my honest thoughts about this particular product!

Okay, Logitech G502 Proteus Spectrum review, here we go!

Product: Logitech G502 Proteus Spectrum Gaming Mouse

My Overall Rating: 4.5 out of 5 Genius Stars

Bright 4.5 Star

Hidden Buttons?

When you look at this gaming mouse, it looks like it has quite a few buttons on it.

But what if I told you it had 11 in total! You might be surprised because if you do the math, there doesn’t appear to be 11 buttons on it.

That is because there are some hidden buttons built into the mouse.

The scroll wheel has a couple of hidden buttons so that if you move it left, right, or down it will activate different mechanical switches within it.

The scroll wheel also has an adjustable button below it that causes the scroll wheel to move extra fast whenever you press the button to release it.

By default, this gaming mouse has an adjustable DPI that can go up to 12,000 and as low as 200 DPI just for those sniper shots!

Near your index fingers are two different buttons. One of the buttons is used for making the DPI higher and the other is for lowering the DPI on the spot.

The button in the very center of the mouse is for resetting your DPI to its regular level.

The best part about the 11 different buttons is that they are all programmable and can be changed however you want to suit your needs using the Logitech Gaming Software you can download from their site.

So How’s the Quality?

G502 Proteus Bottom

Although the mouse wheel is made of metal, the rest of the buttons are made of plastic. This doesn’t bother me at all because they are still mechanical switches able to withstand tens of millions of clicks.

The cable is braided to shield the cord and help prevent it from rupturing, which is another plus. The side grips are rubberized and overall the mouse is really comfortable to use.

I feel like there is a lot of options to choose from because nearly everything is customizable. The lights, the buttons, and even the weight of the mouse is customizable!

It came with five 3.6g weights that can be placed under the mouse by opening and accessing the bottom of it.

The bottom flap used to open the bottom of the mouse is held by a magnet so you don’t need to unscrew it and it stays on extremely well.

The sensor at the bottom of the mouse is an optical sensor, which tends to be better for gaming than laser mice because they are better at tracking and more responsive when used on certain surfaces.

But because this mouse is an optical mouse, I need to have an opaque surface for it to function properly because it can’t be used on glass surfaces.

All in all, it’s one of the best gaming mice I’ve ever used and I love the quality. You can tell the engineers put the right amount of effort into this.

What I Think About the Logitech G502 Proteus Spectrum

Mouse Cable Comparison

Honestly, this mouse is amazing. There are barely any problems I can find with it, other than the awkward twisted cable towards the top that came with my mouse.

It really wasn’t that big of a deal though because I was able to untwist it back to normal.

Logitech’s Gaming Software for adjusting the mouse settings was a little confusing for me to use at first, but I got the hang of it.

I love all the buttons that are on the mouse because they’re all placed well. The plastic buttons don’t bother me because they are comfortable and have lasted over a year so far.

This mouse in my opinion is the ultimate gaming mouse for PC gaming! In my opinion, I think it has everything that a gamer could ever ask for.

The Logitech G502 Proteus Spectrum VS the G502 Hero

So there’s another mouse by Logitech called the G502 Hero too, which is apparently the latest and newest version built like the Logitech G502 Proteus Spectrum.

They literally have the same exact design and are basically the same mouse, but with very minor differences.

The difference between the Logitech G502 Proteus Spectrum and the G502 Hero is that the G502 Hero has an updated DPI sensor that can go up to 16,000 DPI instead of 12,000 DPI.

The diameter of the G502 Hero’s braided cable is also smaller than the Logitech G502 Proteus Spectrum. In addition, the RGB “G” symbol on the mouse has a different shape as well when comparing the two.

I can ensure that if the Logitech G502 Proteus Spectrum is great that the G502 Hero with these small changes is awesome as well because if you look at the two they are very similar!

I’m personally going to stick with my Logitech G502 Proteus Spectrum though for now because I feel like it’s a better value to me.

When I use my gaming PC, I always make sure that I have a high quality large gaming mouse pad to go with my peripherals so that they function properly and protect my desk from any scratches.

To me, they are definitely worth the investment. Check out my post on my experience with getting a large gaming mouse pad here!

Well that’s pretty much it! Feel free to leave a comment letting me know what you think, I wish you the best and as always… happy gaming!
