Yeah, it's a great little job that just makes things 'tidy'.
I find the cheap replacement cases never have the same strength spring as the original (they work fine, they just don't have that satisfying 'flick') and I've not found a decent supplier of 'gel' badges for the back of the fob (like the badge on the left of your pic), just the metal ones which easily scratch, so I usually put a bit of clear tape over it :)
