Good for indoor use but what's the point then.  Wind constantly blows the front and back end off. They give you rope about 1/8" thick to keep the center tied down but thats it.  I'm constantly almost daily basis pulling it back down and 19' is not enough to cover a dodge charger even though Amazon says it's enough. I pulled it down one day and it ripped like paper. Had it less than 6 months and regret buying this POS.
