DOSE A GREAT JOB HEATING POOL
we just put this on our pool a week ago. we live in NC. We've had very warm temos %26 decided to start to open the pool. we had a stormy day with high winds %26 the cover stayed so plus there. our pool is heated %26 in 3 days plus the solar panel the water temp was at 79 degrees! our pool has 17 thousand gallons of water to give you some perspective. Cover seems sturdy overall %26 we are hoping to get more than 1 season use out of it compared to the one that was given to us bythe pool company. This one is also not super heavy %26 comes with bag for putting up for winter storage. I like that bonus. Overall so far, no complaints very happy with this purchase.

Decent cover for a fair price
Decent 12 mil solar blanket, hopefully it will last longer than the last (3 years with a 10 year warranty that wasn't honored by another company). Since my pool is 60 feet long and runs anywhere from 8 to 14 feet wide I had to buy two of these 16 by 32 feet long covers, cut them down and make them fit. That is why I only gave 3 stars for fit. I would have liked to have bought two closer to the width required but a custom made (which the last one was and more expensive because of it) this did the trick. Right now the heat pump only runs in the evening (set for 82) with air temps in the 50's and stops running shortly after the sun starts shining and gets up to 84-85 degrees with air temps in the 70's. So, pleased so far, time will tell how long it lasts.

The solar cover is probably the best one I bought and I've been buying solar covers for 30 years now. This one has one seam down the middle and it seems a lot stronger than all the other ones I've ever bought, not kidding this is the truth. I live in Florida where the sun can destroy a cover in one year. I'm pretty sure this cover will last much longer, use proper care.
