Overall, this is pretty much exactly what we needed for our patio. It looks great and does what we want, there are a couple of quibbles: 
1. It didn't ship with instructions. We were able to print them up from the manufacturer's website, but they even then they weren't great. 
2. It's kinda flimsy, even after we added some extra wood (for weight) to the posts and screwed them into the deck. Not a huge deal, but we definitely aren't gonna lean against them. 
3. The tarp doesn't slide very smoothly. It often gets stuck when you're pulling it open or closing it up. Again, not a big deal, but just something you should be aware of. 

We still really like this, though. The price was great and we couldn't be happier making use of the shade.
