Bests & Worsts Reviews from Amazon

I have been a pool owner only 11 years, but have already bought at least 6 or 7 solar covers already. I've yet to find one that really lasts more than 2 years. This cover came as advertised and was delivered very promptly. We trimmed it on the large side so it sits slightly above the water line. I am getting better heating and retention than ever. I left my pool covered for a few days while I was out of town and the temp. rose from 86 degrees to 93F. This is Colorado, so we have pretty cool nights. I've already noticed some flattened bubbles, but this seems to be the case with every cover I've tried. I would recommend this without hesitation until a better design comes along that can endure the weather elements in CO. Don't buy anything less or more than 12ML. I tried an 8ML last year and it was a big failure. Not only did it not heat and retain heat properly, but it wore out in one summer. The heavier mils are much harder to real and I didn't perceive any benefit in the performance and longevity.
