Now that I live in a year-round pool climate I don't have any use for a cover. But at my previous house in MA I had a Loop-Loc mesh type safety cover. It was well made and held up for years. No pumps and no water and ice collecting on it. Come spring, the small amount of debris that sifted through the cover was easily vacuumed off the bottom, pool topped up, chemicals added, pump on and back to sparkling water in a day or so. Highly recommend that type cover.
