Every technical aspect of this mouse is great. I didn't even have to install any horrible apps to make it work. It's a nice size which is great as my hands are too. But the shape is a bit strange for me. I can't explain it, it just feels a bit awkward in my hand like I find with many bulky "gaming" mice. I actually prefer the shape of the much cheaper Redragon M601, but this mouse has its issues. Oh this reminded me that the Logitech MX518 works fine with my USB KVM but the Redragon M601 doesn't, so I had to switch to Logitech. I also can't take all the extra LED bullshit with modern Dudebro gaming hardware, so this Logitech mouse is much more pleasing to my eye. So if you're a teenager who wants to impress their friends with colorful light shows, don't buy this mouse.
