I was amazed at how thick this opaque white solar cover is compared to the flimsy blue cover that I was replacing. And my pool jumped 10 degrees overnight! In fact, here in the heat of summer, I have to monitor the water temperature in my 16' x 48 round above ground pool because it gets too warm (almost 100 degrees!). The 15 round fits the 16 pool beautifully. My previous blue solar covers lasted only one season before beginning to disintegrate and shedding little blue plastic dots that clogged up my filter. I have a feeling this cover will last a lot longer.One downside is that because of the thickness, it's a little bit stiff and harder to fold up. It's also a bit heavier but nothing an average adult can't handle. Another downside is that there are no holes in it so with the pump on, the cover gets covered with water and starts to get submerged. I will probably add a few holes myself to keep the cover on the surface.Overall I am very pleased with this purchase.
