Wow, we had friends from Michigan that had this Shelter and we made fun of them , why spend that much money when a tarp will do. Well, my wife went camping with them and setup a Tarp in a rain storm for 45 minutes we were soaking wet. Our friends arrived and in 45 seconds there structure was up and they were almost completely dry. We return from Camping and bought the Clam right away. It is amazing 1 person setup in 45 seconds. Great for rainy days or for hot days and you want to stay protected from the sun. Even our cat figured out it was better in the clam as bugs couldn't get to her kibble, oh man does she loves her kibble.
