The basket itself is thin braided metal and insofar as no worse than his fellow competitors much more expensive. The mounting plate is sufficiently strong and stable. Only the Klick-Fix mechanism makes a somewhat hakeligen impression.
That the arm attachment is made of plastic, does not bother me. After all, the production technology is mid way so far that plastics can have a higher strength such as metals. Whether the will be permanent so I can not judge. The mounting principle is ok. And more than 3-4 kilos I would one way or another in the other competitors do not want reintun baskets, especially in relation to the driving stability.
Is not ok that the mounting brackets fit only for allerdünnsten handlebar diameters: More like the standard 22.2mm chrome Röhrln in old city bikes are too thick.
Who in the attachment still paying attention, that are really tightened all screws (including the pre-assembled), which was supposed to get a functional bag for little money.
