Well ive had this mouse for a day, not much testing at all yet but my overall verdict so far is that its much more comfortable than i expected i much prefer it over my g400, cant tell about the aiming yet but i love the fact i can turn off angle snapping and acceleration and the dpi seems good

. The only con so far is the silly usb cable, seriously guys its letting down the product like mad! Mine arrived unravelled it and it was kinked at the mouse and is still a bit kinked (hopefully wears out a bit) and its so annoying on my desk, on the mouse mat its fine but as soon as it hits the desk it pretty much induces a mass amount of drag

, if it had a fabric type weave or something it would be so much better, its fairly heavy aswell which doesnt help!.
Other than that (personally major flaw) it is a solid mouse so far.
