The case is solid (tested for a round-trip Paris-Naples), runs well and quietly on smooth ground and in the airports. The handles are well studied and practices. The locking system of the combination zip closure is well designed and easy to use. The internal separation system / calibration is well thought and sufficient. A bellows system allows to give more height if necessary to the bag in dézipant the perimeter (other than zip closure). The only criticism still remains the price, even if some find them reasonable 80 euros, I personally think it is rather expensive (but very reasonable indeed compared to high-end brands like Samsonite and Delsey).
