I shopped a lot of pergola kits and feel this one was a very good value. Assembly took about 7 hours with myself and my wife. Using the Bilt app on a tablet is highly recommended, since it's much easier when you can zoom in and rotate to see how parts go together. No issues whatsoever with holes lining up. The one problem we faced was getting the two end assemblies upright and connected together with the side rails. It would have been far easier with three people - two to support the end assemblies while the third person installed the side rails on top. The instructions don't give any tips. We managed, but it wasn't pretty! I also question how, once fully assembled, it's possible with two people to mark where the plastic feet should sit, move the pergola to anchor the feet and then put the pergola back in place. The pergola weighs 400 pounds. Our patio is shaded from the prevailing winds by the house, so we'll take our chances and not anchor it.
