Bests & Worsts Reviews from Amazon

I bought the big one 20'X40'. It arrived on time, well packaged. The material feels adequate; I.E. it doesn't feel cheap. I found it easy to trim. So, how good goes it work? A lot better than I expected. I put the cover on the pool at approximately 8am. The floating thermometer registered 62 degrees. By the end of the day, the pool registered 68 degrees. Please note that I am using a floating thermometer and the top layers of the water warm faster than the bottom layers. After about a week of use, and moderately cold weather the pool got to 72 degrees. Yesterday we had a nice, hot day the the thermometer registered 80 degrees. Before I got the cover no one in their right mind would have gone in the pool. Last weekend we had the family over and the pool was very popular. If this cover only lasts one season, I would be happy. I am a new pool owner without a lot of experience, so I had no idea on what to expect. But this was a good buy.
