I found the Advaning awning online and decided to give it a try even though most reviews are not very good. It took me a little trial and error to get it mounted. The biggest key was making sure it was all level before you start drilling and installing. When using it I found it can be tough to change the pitch of the awning. Lowering it is ok but trying to raise it, especially when the awning is extended, can be pretty tough. My solution is just to retract it partway and then change the pitch. An awning does a decent job of covering my entire patio, although the fabric is very thin and does not protect from rain – even a drizzle, and it is a good change having the awning in place on sunny days compared to when I did not.
