I got mine last night. I must say I am really liking the shape. I tried it for a bit in wired/wireless I couldn't really tell the difference using aimbooster.com. I will have to game a bit more to see if I can notice. Coming from the G303, the weight difference is hardly noticeable. My only dislike so far are the button clicks, bit more stiff than G303, which is nice for FPS, but in MOBAs the spamming feels a bit off.
