Even the luggage works bags fall apart. The key is to tell the AA gate agent to F off when they suggest you check it. Never check your bags. The metal screws on the luggage works bags are crappy sheet metal screws that should be replaced with either machine screws and lock nuts or rivets. The aluminum rails will cave in if the bag falls off the belt loader from 15 ft up. With this said, anything else will fail far worse. Consumer grade luggage is overpriced rolling dung with cheap plastic wheels.
