Everything was fine except the particle board shelves were too large to fit properly. Whoever packaged the units or cut the pieces made a mistake, I needed to cut them to fit. If this happens to you and you don't want to return it or wait for a replacement just go get plywood, you'll be much happier in the long run
I have had these for a few years. Good size shelves if you are going to be putting excessive weight on the boards I would suggest getting some plywood to replace what comes with the shelves.
