Have the mouse now since about half a year and was otherwise okay, but now the mouse wheel skips (a bit) up when I'm down Scroll. Every few Scrolls down, he leaves an upward so makes surfing little fun and the play never mind, because it is just pure torture ... change fast weapons and co. you can forget it. Have now my old Logitech MX 518 connected (which still runs 1A) and SteelSeries is so died for me, where I'll have no more money.
