SunHeater Pool Solar Blanket - Heavy Duty Rectangular Thermal 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.

Buyer beware! This is a seemingly ok pool cover however after only 2 years (and we kept a cover on it when rolled up) it is coming apart and leaving little blue pieces of plastic (as the small plastic air filled bubbles deteriorate) in the pool which are clogging up the filter and pump, resulting in costly repair and cleaning service. I would NOT recommend this cover. A typical cover like this should last 5-7 years, so I must assume the manufacturer is using low quality material.
