I got a Razer Mamba from overclockers last year. It is in general an okay mouse but I would say no better than my old G7 Logitech which was a lot cheaper. However I have been very disapointed with the build quality. The first razer I got had the two front feet falling off. Razer told me they could not provide new feet so I had to RMA the whole mouse! The replacement mouse has a rubber pad on the left hand side that was not fitted properly and sticks out on one corrner catching your thumb when you are using ther mouse, which is very annoying. Also my second mouse has developed an annoying high pitched squeak from the wheel, which again looks like it will need another RMA to sort out. Maybe I had two bad mice back to back but it has put me right off Razer mice. Has anyone else had problems with Razer build quality?
