To make it short. The price / performance ratio is ok. With regard to corrosion protection one must not expect too much (-1 *) with the supplied screws and attachment parts. I find the narrow almost dainty design quite presentable. My devaluation to another star is mainly due to the fact that through the long and narrow profile of the carrier pipes (square with rounded corners) it is not suitable for luggage bags, which not only a simple hook for besitzten, but also a backup, which surrounds the support profile as a barb from below and so prevent a fall in uneven terrain. (Eg the Office Orlieb bags). Through the profile shape of the surrounding bottom backup can not trigger because the profile is simply too high. Since the profile also still quite narrow, hang the bags (also without backup) rather loosely to the carrier. This can be compensated in the pockets without securing due stramme counter gums which are suspended below.
