Title: Pool cover it is, heater? - not so much
Review: I had high expectations for this pool cover that it would, in fact, use the power of the sun to keep my pool warm. It is a great pool cover, but, in my opinion, a not so good pool warmer. It seemed that the science was good: small, interconnected bubble-wrap-type, clear magnifiers slowly using the power of the sun to harness and transfer heat to the waters below. Unfortunately, the first 6 inches got only a few degrees warmer than the deeper water. I was generous in giving it only 2 stars.On a more positive note, the cover seems to be quite durable, does not tear easily, is flexible and easy to pull across the top of the pool without having to walk around and around the pool fine tuning its coverage.
