This was not easy to install but it is nice. I need to weight it down when it is fully open because even with an 8 to 10 mph wind it blows upward. When I retract it half way I need to still weight it when the winds are 15 mph. It says to retract it with 20 mph winds but I get small gusts all day long because I am on the water. I do like them, but you need to know the issues you will face when they are open.
