I've got one of thoooooose. They're pretty good, except for the following niggles.
1. The 8mm adapter thing is made of cheese
2. The tyre-lever/ chain tool thingies on the side are sooooo easy to lose
3. The chain tool isn't big enough for a KMC Kool
Whine over, otherwise it's a great way to have bike specific allen keys on you, as opposed to the halfords type ones that have a load you never use and no 8mm.
