Best fps mouse

[Paytend01]

The m65 is designed for fps, it has a sniper button also

It depends how you hold your mouse. I hold my mouse differently than my friends so I prefer different mice than them.

is it possible that it is too light?

is it possible that it is too light?

find something of similar weight, and put it in your hand, and see for yourself

I personally use the Corsair Sabre and I like it out of personal preference. I haven't played that much FPS, but I've logged about 400 hours in CS:GO and I haven't really had any problems with it. It weighs exactly 100 grams btw. Here's a snip from the website.

 

The G502 is a pretty solid, well-made mouse, but it's over 100g by quite a bit. Still a great mouse, but better suited for people that like heavy mice. Here's another snip.

 

I personally hated the Deathadder as it has only 2 extra buttons. People say that it has a "super-accurate" sensor, but honestly I felt no difference from my old Dell mouse. That might just be me. It is 105g though. It's not a bad mouse, but I would rather take one of the above over it. Annnd here's my last snip.
