Millenium Saxophone Wall Mount

I bought this wall mount to put my tenor sax into it. But I would not dare to put my sax in it again.

The product has 3 main issues:
First of all it comes without screws etc. I can live with that because I have everything at home. But I do think that screws are a service that is "usual" today.
Second, the wall mount has a non-functional mounting system. The place where you are supposed to put your screws through has an empty space behind it. This leads to the ionteresting fact that any dowel you put in the wall, will come out of the wall again, through the leverage effect of you screwing in the screw. There was no real way I could fixate the wall mount properly.
Third but not least, the weald seam is crap. It literally broke the instance I put my sax into it. Fun fact, I atleast was able to fixate the wall mount, because that part still was on the wall after the other part broke off.
So not only poor qualitiy, it literally is the reason my sax has scratches and bumps now.
