No question, the mouse itself is super for MMOs like WoW and co. However, I can only advise against the purchase! Reason: After an arbitrary time (at many for 5 weeks, other 1 year) wears out 100% the left mouse button to automatically dial a double is generated in one click. I guarantee you that will occur sooner or later. Sometime after googling: The internet is full of people with this problem. The reason: The pin of the left mouse button is kind of garbage that you would have to throw these things individually with Razer through the windows.
Lousy quality! This is intentional so that you nicely after some time a new Razer buys. This was definitely my last!
I have now the Logitech G600 ordered, since I do not want to give up the keys.
