The assembly was done over a week's time( with nothing done on several days) and each time a pro arrived it was different pros or some of the same pros. The basic shed assembly was pretty good, but not one of them could figure out how to correctly put the doors on. The shed is pretty looking, but has open areas that would let in rain and I cannot open and close the doors without kicking or banging or re-adjusting the doors every time! Several of the shelves were installed upside down. The pros were friendly and tried hard, but they got confused with the instruction manual, but I did provide cold drinks to them.
