In my opinion, the mouse is either complete and utter sh*t or has major problems on cloth mousepads, such as the QcK+
The freemove gimmick is a load of crap. It makes it woefully hard to adjust your aim upwards, and it seems that, regardless of my exactaccel and exactaim settings, that moving the mouse left and right is more sensitive than moving it up and down and for that reason, I am returning it. I absolutely despise this product. Looks like I wont be buying from steelseries ever again.
