i have been using that carport for 3 years. It has kept us dry at many an event. The easy-ups sag, saturate and then leak in any significant rain where these things are waterPROOF. Once you know the deal, they can go up in about 15 minuters and knock down in about the same. My 12 yo son is in charge of the canopy and he can do it alone until its time to lift the roof. Then ya ask 2 people to lift the corners of one side, and he puts in the legs, do it for the other side and he takes over alone again. IMHO, its worth the extra time. Downside is storage of all the pipes and canvas takes up room.
