My experience has been mixed. I bought a post-LVMH aluminum Classic Trunk, and its frame has already been bent twice in one single trip. The second time made it quite difficult to open, since the frame was warped near the lock. It was fixed both times for free (despite it being clearly airline damage), but having to take time out to find a Rimowa (which does the repair), drop it off, and then pick it up is a hassle, especially mid-trip.
