The finished product of the pergola is great.  Assembly was not easy, I ended up having to hire someone to assemble for me.  You definitely need at least 2 people to assemble, maybe even 3 at times.  With the posts and screws, there are probably hundreds of parts.  If I move and need to buy another pergola, I would definitely look for one with an easier assembly process in the reviews.  The actual product is beautiful and has been up for almost a year with no peeling, color issues, etc.
