I have both a Naga and that mouse which has been boxed for months now. The build quality on the WOW MMO mouse is terrible and its not a nice mouse to use. I had to return it after a week as mouse one failed and wouldn't click anymore, the replacement I got wasn't much better.

If you looking for a great MMO mouse for wow the Razer Naga is amazing, it really is a great mouse and comes with its own software to set your interface up inside wow to match its layout.

Going back to your question, I wouldn't recommend the WOW MMO mouse.
