I bought this just in case it turned out to be useful, since it was pretty inexpensive. I have been using it for about 18 months, it's held together very well and it turns out to be very useful, I think carrying a my lock on my belt works a lot better than putting it in my bag or in a frame mount. Probably because the weight of the lock doesn't bother me when it's being supported by my massive ass.
Mostly I'm writing this review to tell people that I think the sizing in the description is pessimistic. As you can see from the photos it fits the Kryptonite New York Fahgettaboudit very comfortably, which you'd probably expect, but it also just about fits the beefier Litelok X3. I wouldn't want to try anything bigger than the X3 though.
I'd love it if there were a more expensive one with a needlessly fancy closure system or something, but I'm very happy with this thing as it is too.
