TechSpot: Logitech G502 Proteus Core 12,000 DPI Gaming Mouse Review

Having only been available for a few weeks, we're surprised by how many people have bought Logitech's new G502 Proteus Core and perhaps even more by the fact that few seem anything less than enthralled, whether by its style, specs or simply its badass name.

Being the first mouse to tout a staggering 12,000 DPI is of particular interest to us because it should be ideal for 4K gaming, though the G502's advanced sensor is complemented by a host of other features that also make for the ultimate gaming companion.

The device is super flexible, working flawlessly on a variety of surfaces, not to mention its five chevron-shaped 3.6g weights, its eleven programmable buttons, in-game DPI shifting and dual mouse wheel modes.

I picked one of these up shortly after launch and I'm pretty happy with it. Came from my old Razer Mamba. My only issue right now is that the scroll wheel isn't my favorite. It has 2 modes - locked (so it clicks) and unlocked (so it spins) and neither really are perfect for me. Overall though I'm pretty happy.

Does this buzz/squeal like every other high-end Logitech mouse? I've been through several replacements and different models (Performance MX, G500s, G700s) and while I really liked them, they all emit the same squealing noise so have been returned.

Do you have a tumour? Kind of a bad joke but honestly I have used half a dozen in the past few years and never heard that. Also never heard of anyone else talking about it.

No, it's a well known issue. If you have a noisy computer or less than perfect hearing it might not be audible because the noise frequency is just inside the audible human spectrum. It can fixed by replacing one of the capacitors (I've done it with my older Logitech mouse) but I'm not willing to void the warranty on a brand new mouse to fix an issue that shouldn't be present.

Have you tried the mouse on another PC? I have seen the noise issue occur when a motherboard is going bad. Something about the sound card/chip and USB port.

Holy crap, you're right, I just pressed my Performance MX to my ear and I can hear little noises. How strange!

Can only hear it if I actually hold the mouse to my ear though

I gave a Logitech G700 and I'm still trying to figure the comfortability in the g buttons. The 4 on the left side? I wonder the way these are placed are much better.
