It took me several months to write this review because I held onto these before I was ready to start my project. I bought two so I could turn a large doorway into a built-in bookshelf. These worked perfectly. The instructions were easy to follow and I was able to mostly do this myself. I had a little help from my son a few times. The shelf is solid and sturdy! You never know with these kinds of shelves but I feel confident that these will hold up. Everything fit right and all pieces were accounted for. They don't look super cheap. Definitely worth it.
