I just returned from a trip with a Luggage Works bag that's been in use for about 15 years. The only maintenance it has required has been new wheels; I use inline skate wheels and bearings, replacing them every few years. It's as solid as when I first picked it up at the stop-over store. This bag always gets checked. It's never a problem. Not to say it wont' be one day, but I've had a lot of mileage out of this bag; the only complaint I'd have is that it's heavy, empty. Otherwise, none. I wouldn't use anything else, personally.
