This is not a bad unit. It took us 4 and 1/2 hours to put up. Fed x delivered the item and beat the heck out of one side. Wayfair was great in getting replacement parts. You got to use at least 2 to 3 people to put it up. You got to be careful and not bend the roof ribs. One of the corner poles was not square so we had to do some work to square it up. It is nice we hung lights around the out side and curtains on the sunny side. Just set aside the time.
