Good to know, thanks for the feedback.
No probs. I always try these mice eager to like them, ready to whip my wallet out at lightning speed... but it rarely pans out. The only one I've been impressed with recently is the G403, I got to try it at the EB Expo. The Roccat Nyth also impressed me a lot except for the fact that the left and right clicks - arguably the most important - were stiff.
By the way I found a trick to try before you buy:)
At EB games, they gut all their hardware and just put the box on the shelf. Since the mouse is already removed and sitting out the back, if you ask nicely enough they will let you try it. I basically said to the guy "since it's already opened, would you mind letting me give it a quick test? I don't need to use it on a PC, I just want to get a feel for the ergonomics, the buttons etc"
He was more than happy to oblige. Saved me $150...
