I am surprised at the high reviews for these patio chair covers. We bought 2 of them  in June 2014. Last year they started ripping and when I tried to clip the opening they crumbled in my hands. Unfortunately they only had a 3 year warranty. This is not a case of an individual bad one. We also bought the oval table cover that goes over the table and side chairs. It ripped in several placed before the warranty ran out so it was replaced for free. Maybe the newer ones are better made??
