Some initial impressions
-No rattle on the scroll wheel, between me and 2 other friends I was the only one to get one without a problematic scroll wheel.
-Mouse feet are really fast, unfortunately they feel scratchy with fast vertical/diagonal movements.
-I like the shape, it definitely feels like a hybrid between a 3.0 and 518. I could also describe it as a more compact G400 without the lip.
-I don't really have any complaints about the cable, I'd rather having something...
