SwimWays Thermaspring Solar Mat 6 Pack, Blue

They seem easy to use, overall, and float even when not inflated.However, it's annoying that the battery-operated inflator I have couldn't be used to fill them, and when I inflated them myself, one of them immediately popped.Still... as I said, they seem to float just fine without inflation, so I'm not sure why it even matters, frankly.

I like the shape of these pool warmers because they fit nicely in our pool. I have had bigger ones before & they are more difficult to get out of the pool & then you have to put them somewhere until you are finished swimming. And they cannot be stacked on each other, so it is hard to find places to put the bigger floats.

Significantly smaller than how they are advertised. Doesn't not hold air well. Only lasted a week before they started sinking to the bottom of pool. Absolute garbage! I purchased 3 15ft above ground covers for my inground pool for $60. Better coverage, better material, and easier to use.

I purchased this product to help raise the water temp. in my pool. They don't do anything! Also was shorted one item in package. Not worth the money!
