This is the complaint I sent to Doheny's: So, this cover was bought last August and put into service immediately. It was pulled off, rolled up and put into my storage shed for the Winter about mid-September. It was pulled out and put on the pool at the beginning of May 2024. It started bleeding plastic pieces from the bubbles in July. Later in August, when I was pulling the cover off to swim, it ripped. It didn't catch on anything. It just ripped from my pulling. It always goes back on the pool after the swim. These problems shouldn't be manifesting on a cover that has only about 4 months of total usage. My last two covers, which I purchased from Doheny's, both lasted 3 seasons. I didn't save my receipts from them so I couldn't make claims. This last time I did. I am very disappointed this time around. The cover did a fine job heating up the water. It just fell apart. You state the warranty doesn't cover the bubble damage due to an unbalanced pool. Really? And how long would it need to be unbalanced for it to eat away the plastic? One day, a week, a month, the whole season? An unbalanced pool would be an uncomfortable pool to swim in. My pH is always where it should be. I assure you my grandkids and my wife would surely complain about the water quality. I run a simple ionizer, which I've used for about 9 seasons. This allows me to use LESS chlorine. So, that can't be it. I also use Easy Care Pooltec algaecide. There is nothing in it's information sheets that says it will harm plastic. That's all the chemicals I use. No need to use pH adjusters because it's never out of whack. I really don't think ANY cover will make it to it's warranted life expectancy. But, it surely should last more than 4 months. I expect a fairly decent credit towards another cover. After a month, no reply. DONT DO BUSINESS WITH DOHENY'S!
