Review on Sun2Solar Clear 10-Foot-By-16-Foot Rectangle Solar Cover 1200 Series Heat Retaining Blanket For In-Ground And Above-Ground Rectangular Swimming Pools Use Sun To Heat Pool Bubble-Side Down by Brandon Pratt

First, the good: This cover, or one like it, does a great job of keeping the heat in the pool overnight. We used a roller so taking it on and off was easy. The 1200 series was fine. A thicker one would just be heavier.The bad: The seams were never properly aligned. There were wrinkles and gaps and the cover would never lay flat. We used the cover for 2 spring seasons and two fall seasons so a total of about 18 weeks. Between seasons it was stored indoors out of the sun. By the fourth season, this fall, it was coming apart at the seams and had more or less ripped in two. No issues with the bubbles coming off.
