content: I bought this mouse for gaming a couple months ago and have really enjoyed it's features, particularly the on-the-fly resolution adjustment. I don't think the third button has a real use, however. The real problem lies in the fact that the left mouse button has become nearly useless. Every other click now either goes unregistered or double-clicks. This is apparently a very common issue, as I have discovered a lot of online forums concerned with this issue. I've gone back to my Dell optical, and will probably never buy a Creative mouse again.
