10 out of 10 in my book. It warmed my pool water up so dang fast. Easy to throw on although I would definitely recommend one of the reels for the solar covers because this thing is not easy to pull out of the water.

This solar cover is great. Very simple and lightwieght and thick for a solar cover. Does a great job of keeping the heat in and doesn't rip or sink when wet. I would deffinatly recommend this solar cover.

This is really what it says it is, the length is right and the thickness is to. I will say that I have a clear one to and the blue and clear are no difference in the way it keeps the heat in. So its really just what color you want..

Love this solar blanket and it does exactly what I wanted it to do. I got a larger size so it could be used as a solar blanketcover. It was easy to trim down to the size I needed. It’s thick and durable, very well made.

This pool cover is perfect. I like the clear color so i can see my pool water through it. I've had them before and they do a great job keeping the heat in when it's too chilly to swim without heater on. We don't lose heat overnight like we used to.
