The total expense with this bike rack is enormous. First, the customer should be made aware of the offer that he receives this support only in individual parts and assembly, even for a good handyman but needed 3 hours. If something does not work then the trouble really gets loss, which it must e-Mail`s be written. In this case, 3 x were expanded lighting sets after they have been reviewed in a specialist workshop as the operability was not given. Now, the third set of lights is installed and it still does not work the reversing light. the workshop confirmed this. The manufacturer, however, a German TÜV certificate is submitted. I can not imagine that the TÜV issues a certificate when a reversing light is not functional to me. This fact is based on the connector to the lamp set which is 8 -pole and the socket on the vehicle has 13 poles. As compensation for these expenses throughout the company offered then 20, - discount on (3 times go to the workshop, can consider 3 x 3 times and go home). Cost of at least one price reduction of 50%. So my advice Vorsich with purchases at the company "Vonderpalette"
