Bought this last week, for granddaughters Christmas, 4hrs into it today....almost done.  Instructional is almost useless !  Actually, there are only steps w/diagrams, not verbage to check for which side of the panel you're working with (example). Elevator was a nightmare ! Grooves in wooden dowels were too shallow, screwed up dimensions on the entire elevator. All-in-all, its still better than the Barbie/Chinese garbage......but not much.  Should last 2yrs, if not moved often.
