Functionality: It works, the shades is flushed against the house, no direct sunlight. There's still plenty of light under the shades. We got rain yesterday, no rain hitting our patio door/steps.
Installation: If you are doing a 3 pts (Triangle) or 4pts (square) then I would assume it would be much easier. We had 5 points sail, so installation was tricky and very frustrating. You now have 3 different anchor points pulling the sail in different directions along the track. I had to take install/uninstall multiple times to get shade to align inside the track. Basically, we had to come up with our own method to install and aligned the shade.
If there was a way to hold the shade in place, I would have rated this as perfect.
