The quality is what is expected and historically delivered by Sennheiser, you will not be disappointed. The molded wheel cups fit different width wheels. If you still dont understand why anyone would want it, that is ok, you really dont need to worry about it. The flat hooks fit very well on top of my doors and you cant even tell its there when you are opening and closing the door; its very smooth. Also, the stitching has started to unravel. Im going to stick with Alpine, kenwood, pioneer, jvc. I assumed this was simply becaseu of it having been folded and that it would straighten out as I loaded it with the weight of the shoes. It attaches easily to the stand but make sure you have the right stand. Les vendeurs de casques savent enfin que la France existe! Really like this product, easy to use and easy to assessment
