I had this mouse with my asus G73SW and the passage of a normal mouse to a typed "gaming" the beginning gives the odd feeling, but after two days I found this mouse is decidedly more pleasant this I've never tested. Matt finishes are very pleasant to the touch, the hand fatigue, absolutely not, even if we go all day with, I take it to work for the CAD and 3ds and then home to play occasionally. Accuracy is not bad at all, choose between several dpi is helpful.
However, after two years of heavy use the left click and started messing meet once 3 finishes were peeled in places, so I decided to order one on amazon to discover the same.
I recommend this product to amazon price, this is really really not bad!
