Very expensive and not worth the money. Too long for delivery. Too long for installation. The Corradi Ididium retractable pergola roof leaks around the edges and the authorized dealer says “that is normal”. I know for a fact it is not beause I speak Italian and called Corradi in Italy. If I wanted a product that leaked, I would have purchased from Home Depot! I cannot and will not refer Corradi to any family or friends!
