We love our pergola! It looks so nice and has held up very well through one MI winter so far. The only reason why I gave 4 stars was the assembly.  My husband and I put it together (mainly my husband alone) and took our time over about 2 days outside of work hours. The roof pieces weren’t as thick and durable as I’d hoped and were a pain to stay together putting it all up. Once done though, it works great and have no issues.
