Class suitcase, can withstand a lot. Due to training so much traveling and only with public transport. Thus, the case is already rolled several kilometers over different floor coverings and does everything with super, after one year no signs of fatigue of wheels, telescopic handle, etc. Only the capacity could be a little better, at least for my needs. The given 21 liters seem a bit tight or with it, distributed unfavorably. But anyone who has to carry only a laptop, a record Norder, few documents and writing utensils, which is well advised with this case.
