All parts are well labeled and the structure is simple. The only drawback in this case: There were no matching screws for our Samsung TV, which surprised me, as every 3 sold a TV of the same brand. Anyway, the screws have not cost a euro at the hardware store - alone the effort was annoying.
Before further trouble you can ebefalls protect if you have a separate spirit level. But then this use in doubt, place the enclosed.
So far, the TV hangs and will hold so hopefully continue.
