Seriously, get the directions fixed!  Completely unacceptable.  We may have to return as the directions are so incomplete.  We read SO many bad reviews because of the directions and should have listeners.  Hours in and have had to take it apart multiple times.  There are 3 key sections that are simply not markedexplained.  HORRIBLE.  I think we would be better off with zero directions.  DO NOT BUY IF YOU ARE NOT AN ENGINEER.
