This is the second rectangular market umbrella I purchased. The first lasted through the Spring Summer season of 2018 here in the Northeast, but the spring wire popped out of the retainer and broke a lift arm when it fell in August. I was retracting the umbrella and thought I may have done something wrong so, I ordered another, which I didnt use until yesterday. Within the hour of raising the umbrella the same fault occurred (as mentioned by others). Since the umbrella has a mere 30 day warranty, I am pretty much screwed. DO NOT BUT THIS UMBRELLA. It has an inherent engineering design fault and will certainly break. The only question is When will it break.
