got one here. also got zowie s2, dm1 fps, mastermouse s, logitech g102, ninox venator here and used (=owned) zowie ec2a&b, za13, fk2, razer deathadder, mionix castor, rival 600, finalmouse air58 and intellimouse optical in the past. probably more i forgot.
aim is best with mastermouse s but quality sucks, sidebuttons suck, even with paracord, hyperglides and removed weight i still prefer gpw overall. my aim is slightly worse than mastermouse s, same as with zowie s2. but gpw is well... WIRELESS, lightweight, best quality i've ever seen on a mouse, clicks are good, shape is almost as good as mastermouse s and works for many different grip styles. amazing piece of tech. haven't switched back to any other mouse since i got the gpw, before i constantly switched and tried different mice. gpw is too good.
