I've now been with the suitcase in the States and could bring clothes for 3 weeks without problems. If you follow the instructions, the hardest things to accommodate "roll-close", the case is also very stable in the state and with relatively little pressure to roll in hand. Physics precisely because neither the trunk nor the manufacturer do something - Who grabs wrong, you can not expect that it works stable.
Even after a tour and life-of-the-suitcase etc. I can not fatigue determine.
