I then but prefer more spent the few Euro, as in this case, the linkage and the handles is better integrated into the shell of the case and I hope that the case will thus accompany me on longer trips.
The roles are pleasantly smooth and not completely hard plastic so that it does not roll scraping or scratchy on hard marble floors.
The interior of the case is, of course, with the straps and thin zipper flap of the cover part a bit spartan, but more would be for me even more unnecessary ballast. I suppose if necessary rather a few plastic bags with to keep the suitcase contents apart.
