I bought these to hang over my kitchen sink and they turned out adorable! I would try to put as many of the screws as you can into a stud or a drywall anchor at least. They hold as much weight as advertised, I haven’t really tried to put much more on them yet. I really love the sleekness of how they look and they seemed fairly easy to install. Price was great and I only ended up using two in the original location and will probably put the other in another spot in my house! They come with a variety of hanging hardware for drywall, studs, and concrete. I had an idea in my head of what I wanted it to look like and these worked perfectly for me! Would definitely recommend to anyone who is looking for cute, floating, decorative shelves!
