I have kept one of these pools up each summer for 4 yrs. I buy a new one each year, so I do not worry about the cnance that I have set it up and the ring goes flat. I am impressed that the ring stayed up all season this year, usually a small leak wil occur and inflation need to be done frequently. It is perfect size, easy in and out with small step outside and easy upkeep with shock weekly and the floating clorinater. I also keep a case of filters on hand to insure a clear filtration. good buy
