I really wanted to give it a 5, BUT,  a few things.  It would have been nice for the direction booklet to be on top of the unit instead of underneath everything.  I didnt find it till I was almost done.  I printed them out with over 25 pages.  Letting u know the booklet was at the bottom of box 1.  2 nails had no head and a dowel was cut in half.  But there are spare parts.  So it wasnt bad.  The parts were in bags labeled  for each step.  Amazing. It is a heavy and well built unit.  Approx 150.  I am definitely happy with it.  I would recommend this unit.
