This shelf is good and durable. As I filled the containers, I realized how much weight they were supposed to support. It looks good. I'm giving it 4 stars instead of 5 for two reasons. Assembly would be a lot easier if it weren't for the small screws, but that's ok. Basically, the upper part is curved. Instead of sending me the part, they wanted me to send the whole thing back. Too much effort so I just stay hunched over. Hey, it's a garage organizer - who cares?
