One of the shelves arrived with a chipped corner, which didn't really affect me as I had only planned on setting it up 4 tiers high anyway.  It went together easily and is fairly sturdy, but does wobble a bit - even after I made sure all of the sections fit tightly together.  Fortunately, I bought this to put in a corner between a chest of drawers and the wall so there won't be any chance of bumping it.  It serves the purpose I purchased it for but wouldn't suggest it as a rugged piece of furniture or to hold anything of value that could break if the rack is bumped and tips over.
