So glad we purchased this gazebo. It was a challenge to assemble but everything was clear between the paper instructions and the Bilt app. Using both helped us confirm a few tricky assemblies with the roof panels. We did it with two people until the roof panels went up. Four is just right. Having several ladders was ideal. Best to watch the video and sort out the hardware and lumber by number before you plan to do the build. It turned out beautiful, smells wonderfully of cedar, and we began using it immediately. Two trim pieces had some plastic packing melted on them that we couldn’t remove. I emailed customer service and they were replaced immediately. Shipped within days. No regrets here. Highly recommend!
