They are everything I wanted for the aesthetic I was going for. They are a fairly simple install and they come with pretty good instructions. However, I don't know if it was my rush to get them up or if it was a design flaw but they are not very sturdy in the wall. I had seen a few reviews that said that they were a bit loose and I wasn't expecting heavy objects on it but I did end up needing to put support bars underneath them just because they kept sinking downward. Had I known that would have been the case I would have installed them differently and avoided putting holes in my wall at all but they're up now and it is what it is.

Can I say these are the perfect shelves for home decor? Yes I can. I love these shelves. They gave my walls some well needed decor upgrade. Only downside it that the cords are not removeable.
