The wall mounting mechanism is awful. There's a metal sheet that is to be screwed into the wall and then screwed into the floating shelf. The problem is that there are no holes in the metal sheet. You have drill then yourself. My nailbid couldn't make a hole. I texted the company which recommended pounding a nail though to make the pilot holes. Man that would be easy if you a shop set up in your garage. Not gonna happen in a condo in southern California. I was forced to either return it or buy a metal sheet punch. This 30 minute project just turned into further work. One suggestion, send the bracket with premade holes. It would cut time by a lot. Very disappointed. I would recommend not buying this particular shelf.
