The return address is to Letchworth Garden City in Hertfordshire so the return postage is about what you'd expect. I sent it recorded delivery just to be on the safe side which came to about £3.50ish, I can't remember exactly.
Got a responce from him just now saying my mouse was posted back on Friday so I hope to get my hands on it very soon. It'd be nice if there's some sort of sign of the new design working, but I doubt it somehow. I just hope it fixes whatever caused this obvious flaw.
V-Spec if you want to get this guy from Roccat's email address give me a shout on MSN (my address is in a post above) and I'll forward it to you. Otherwise you'll probably end up with another mouse with the same design flaw, much better to give this new mouse wheel a shot.
