The carrier is largely stable and makes a tidy impression processed, only a few fiddly plastic and rubber parts reduce the impression. My delivery was a self-locking nut without thread - in domestic fundus or at the hardware store you can for pennies but quickly get a new one. The wheel to the cart back has pretty twisted when tightening the fastening screws, which the function but not significantly impaired. When assembling the three normal-sized adult bicycles you would have to tinker a bit. For a ladies bike and a child bike I ordered additional crossbars. The now remain but are useless in the corner: The ladies bike has a fairly high frame and the link from the carrier to the bicycle is too short to achieve the additional crossbar; the wheel can, however, attach securely beneath the seat post. The height difference between the second and third wheel is so great that there can not succeed to connect from crossbar to crossbar. But again, let quickly find another secure mounting option. A small shock has given me the assembly instructions to the end: It looks at first glance as if could just a load of 15kg in total to be charged. However, This refers to 15kg per wheel, so when LOGIC III total of 45kg (as it identifies a label on the carrier). A small test with a bathroom scale and a person wearing a bicycle, has shown me that our adult bikes weigh slightly or significantly higher than 15kg. Three big bikes or e-bikes should then probably rather avoid. In this regard, I would find a note in the product information on the Amazon page helpful.
