From this base support I would have hoped for more really. It might look chic, easy to assemble, but for the price should be in there more. The locks are operated via a plastic key. Here, if the key is not attached properly, then turn the key the plastic teeth around. That must really not be solved so cheap. In the first ride without a roof luggage was lost almost a corner or end cap. If that would have flown away to me, the noise would be even worse. I use these sources in the Audi A3 Sportback and it's not just a Buzzbox. Until 130 it's still just so, about just too loud. When I put on my Thuledachbox, the noise verringerb significantly and the box must be driven only with a maximum of 130 kilometers per hour, so the team in total acceptable. If I had the choice again, I would make up my mind now for a stock of Audi, as I have at least not heard of my colleagues mentioned the negative points. I have the support subsequently masked with Coroplast and thus secured the end caps, thus, he has become even quieter. If you can live with the points or better who refinishing gets an aluminum base carrier which does its job. From me there for the entire work but only three stars and thus only a conditional purchase recommendation. If you keep this version for helpful, I would appreciate a review.
