Ok. So I am not a hardware person.  However, the directions on this were excellent and they came with a built in level so that the shelves are straight!  The shelves are not hanging slightly one way or the other.  They look awesome.  The finish is great and the shelves are deceptively light.  They are fantastic! My son has them in his room for his special personal items.  

Pros: Highly recommend these light, attractive, well-constructed and hardware friendly shelves.
Cons: None.
