It’s a solid pergola. The installation was easy just a bit tedious because there were 27 roof slats to put in. Once you have the main body of it up you can solo this project. It took about 4 hours to complete from opening the package to it being fully up. When the roof is closed it does a good job of sheltering you from the rain if it is t coming from and angle. The product seems quite solid and should hold up over time. I E had it for about 3 weeks and we have had some good rain and it’s still working like day one. It is a very modern looking pergola and really stands out in a good way.
