I just bought this a few weeks ago and my husband and brother in law put it together yesterday. It took them about 6 hours to do which I think could have been done in less time if the pieces had some kind of labeling on it. It was kind of confusing to figure out which piece the directions were talking about. Also some of the holes didn’t line up with the other ones when connecting it together. Overall though it is a very nice and sturdy pergola and a perfect addition to our patio.
