I purchased a Rimowa Stealth 26" one year ago as my Tumi(s) (20" & 22") were too small for longer international trips.
I understood the suitcase would dent and scratch and look tattered after several uses. It has, but that doesn't bother me. It has been broken on 4 separate occasions - broken wheel, busted wheel bracket, broken handle and shattered lock. Each time it was sent to the service center and returned, fixed in 2-6 weeks. But I have lost all trust that the suitcase can handle a 2-3 week international trip with multiple check-ins.
I have been flying for 10 years, 150-200 days a year and never had a problem with the Tumis…I'm going back as the Rimowa experience has left me with too much anxiety that my contents may not make it back safely.
