If I was rating just the shelf itself it would be five stars.  The finish and size are perfect for my office and it arrived quickly and in perfect shape.  BUT the hardware is a joke.  I am very familiar with the hanging system as it is one used on Ikea floating shelves so the design is good but the mollies and screws did not really work...It was easy enough to put the mollies in the wall but the screws never tightened...they just keep spinning.  I tried to use other screws with them but that did not work either.  I did manage to hit an area with a stud so at least I was able to use wood screws in 2 holes.  I have the shelf up but I would never put anything of any weight on it unless I took it all down, and used some other anchors.
