This unit is very nicely made, and far better quality than I expected for the price. It arrived right on time, and with no damage at all. My husband put it together in a couple of hours. Instructions were clear, and the many parts were very clearly labeled. The only questionable part was that the instructions have you assemble the entire thing (attaching the top half to the bottom half) before installing it behind the toilet. That seemed almost impossible - it's pretty top heavy and cumbersome so lifting it that high to slide behind the tank would have been pretty difficult. We put the bottom half in place behind the toilet first, then attached the top half and doors. Worked like a charm.
