Other criticisms mentioned earlier, I have but can also eliminate established:
Cross member must be installed only by difficult or 2 strong people. On the one hand properly, but there are alternatives. I have the support (left in the direction of travel) unscrewed from the frame and latched into the crossbar. Then I the crossbar together with the holder clamped obliquely between the two sides and then pulled straight up to the screw that goes with little effort. Then I screwed the bracket again. For single building that is the ideal solution for continuous disassembly / assembly, for example for space-saving transport, however unreasonable, also because it has to have a screwdriver always. As the manufacturer should come up with a solution, such as an articulated joint in the cross brace. Thus one could use the cross bar and convenient by simply pressing down create the necessary stability for the voltage.
Trailer is not level when 28er bike. This has bothered me and put up with a solution: I have (90 kg) was carefully placed on the mounted drawbar and rocked while until a slight bend revealed and showed the drawbar minimal upward. Now the trailer is absolutely in the balance. Something you can balance the bike, by giving some angle there even when the coupling assembly. The flexible coupling on the drawbar adapts.
Despite these shortcomings, I forgive 5 star, given the low cost and because the trailer is otherwise perfect, it is light and runs quietly. You hardly feel it while driving. The proposed change to the cross brace would be desirable, but would probably increase the cost of the product.
