Worked, until the wind ripped it apart
Constant movement from the wind and poor construction led to several problem areas after 6 months. The material faded and had wear holes. It creaked with every gust of wind which was annoying as hell. When a storm finally put it out of it's misery, I was almost relieved. It did do it's job for about a year though and was nice shade from the beating sun. Great concept if only it wasn't a cheap, China-made piece of crap. Slightly better materials and construction and it would be a winner.
ProsIt shades you from the sun and is adjustable.
ConsEverything I listed in my rant.
