The case is functionally great. Easy to grow by wide sturdy wheels. Very spacious. We now have it about 4 months in use and are thrilled. Initially annoyed us the smell, despite the outside air for a long time continued with us, but now it has almost set. To date, he has two air travel and a few minor Wochendreisen unscathed. The best we like that you can set it higher or lower, depending on the space required by zippers. So it is suitable for short trips depending on both one and two persons. It is easy to distinguish from others on the airport treadmill by the wide belt. We would buy it again or are we perhaps a larger set if necessary still. One point deduction is only because of the smell.
