Just a rant. Started opening today and my cover just gave out, tearing at the seams. I shouldn't be too upset as this one lasted six years. Usually they only last three years. This is because I installed a non rectangular pool and the automatic cover runs over the concrete and just wears out. My biggest regret is not putting a rectangular pool in and have it run under the coping. Probably would still be on the same one after twenty years. So take note if you want an auto cover.
