SunHeater Pool Solar Blanket - Heavy Duty Rectangular Pool Solar Cover with Bubbles - Heat Transfer Solar Pool Heater for In-Ground Swimming Pools - Durable 12 Mil Thick Polyethylene - 16' x 32' Feet

Seems solid and well-made. I use it with a reel and find it saves on both heating and evaporation of water. Yes, it takes some discipline and effort to put it in place but I feel it is worth it, especially if you do not use your pool every day. Regardless of brand, I have found these only last about two years (in FL) before the plastic starts deteriorating. Warranties only cover "defects in workmanship" but not longevity. I have tried the clear version and found little difference - it's mostly a matter of taste.

La cubierta está en buen precio pero viene muy mal unida, se hacen muchas arrugas

Works well. Was surprised by how much heat it holds in, about 2 degrees a night ( during moderate weather) which adds up daily with a pool heater, especially as you first warm the pool. If the sun is out will heat a little faster with cover. Can be folded out of pool and back in, with 1 person.

I am honestly quite shocked at how well this works. We open our pool late April but the water temp hovers around 70-75 until june at least. I prefer 80+. I had been leaving the blanket on all day and night since the daytime highs are only 70-80 and windy, not ideal swimming weather but sunny. We had a few days near 90 which helped heat it up. Without the blanket we reliably lost 5+ degrees overnight, but now it retains that and has heated up much faster. We’ve been swimming in 80-85 degree water since mid May, even for my daughter’s birthday party which we’ve never been able to do! I was lucky to get the 18x36 for an amazing price, the only reason I gave it a try in the first place. It wasn’t too bad taking it on and off, but we just set up a reel yesterday so now it’s a piece of cake. Love this!! It’s really thick, not flimsy at all. Wish I had gotten one 2 years ago :-) The picture shows this mornings outside temp at 67, and pool temp at 82. In even bought a depth temp sensor to test the temp several feet into the deep end, thinking these blankets just heated the surface of our 16x40 pool….but that’s a consistent temp even 5 feet down. Just saved myself $10k for a pool heater and gas line.

Works well to keep pool warm but does deteriorate over time with sun.
