This is a great pergola kit that is reasonably priced. I agree with the other reviewers about using the Simpson Strong Tie brackets from Home Depot vs. the ones sold by New England Arbors. We had a contractor install it and said it wasn't too difficult. We have a few hiccups in the install. First the height hit right in the middle of the windows to the house so we had to order the extension posts which took another 2 weeks to get delivered. This is probably because our house has a crawl space underneath so the windows are higher than usual. I'm giving it 4 stars because it sways a little bit if you lean on it hard and the shade coverage isn't very good unless you get the canvas strips which we ended up ordering after installing it. Overall it's a great buy.
