Top Wall Mount

Negative reviews of the product, I can not understand. The quality of the wall mount is whether the price much higher than I expected. He is also thought out functional, because the unfolding of the struts, if it is not needed can be easily accomplished.
Theme "two bicycles hanging": This is of course depending on what you have for bicycles. For two mountain bikes I would not use it. Just make it: If your bike closely and then measures the required length of the strut. And you then asks if you thus can live, that the bicycles can be possibly caught each other.
For me at least it was not an issue. I have per Fahrrard to hibernate a holder and behind the parasol.

Thread mounting hardware: Although I could not use it anyway, because wooden wall, but both dowels and screws are sufficient for hanging on a wall. The supplier can hardly settle for any wall texture all solutions.

Thread quality: I have not even checked whether scratch etc. exist. It is not a piece of furniture but it's only wall bracket in the carport. The thing that counts for me is the stability of the material. And that's great. I can not imagine that it ever can therefore give me problems. And if the foam is eventually worn, then I wrap a new over.
For the money, absolute recommendation on my part. Ask me anyway, that will ever happen for the price.
