This is a nice unit for the price. While assembling, one of the sides was off by a half inch. It was a pre-cut, pre-drilled piece and could not be modified to fit correctly. Once finished, there were other pieces that hid the mistake but you could still tell it was not right.  When you are sitting on your floor with a hundred pieces around you, it's not really the right time to just stop and try and order a new piece.  Plus, the directions are not very good. They have limited wording and the pictures do not exactly describe which way the pieces go together.
