Anybody Ever Used One of These

I am looking at this for a picnic table shelter.

Any experiences? Any personal review? It seems that it starts to rain just about the time we sit down to eat on every camping trip. Im just trying to prepare for that.
Well, and the campground at Brown County where the Indiana Spring gathering is taking place has a distinct lack of shade.
