Just received my rev 3 in black - fit is so-so I'd say and certainly not as tight fitting as the original fitted surround, but then the original is much thicker so it now feels a little unsubstantial with the rev 3 surround though without the bulk of the original. I'm going back to use the original as the quality of the plastic of rev 3 isn't quite there yet but may revert to the surround when I need to carry my key set in a pocket without the bulk - when cycling on the odd occasion. It's a great concept and one Mini should be considering themselves but it needs the right material at the reduced thickness compared with the original surround and perhaps plastic doesn't make the grade - in metal or carbon may be? With an offer of free postage applied and a product cost of $12 it's no great loss but in retrospect I think $6 to $8 is nearer the mark for the volume in materials of the product and maybe better waiting for rev 4 or 5? Came with a lot of packaging (large box and bubble packing for such a small item) which isn't very eco as a padded jiffy bag would have been quite sufficient - just a thought.
