I love this shelf, but gave it four stars because of the directions - sometimes I put the piles in the wrong slots or facing the wrong direction and had to take all or part of it down and begin again.  Also it comes only with the Alan wrench, you have to have the other screwdrivers which most do, but I don’t. So I had to stop and borrow them. It’s fine now and I love it. But I would not want to put it together again.
