Title: Yup it works!!
Review: We were averaging out at 84-86F everyday in the pool. We slapped this baby on top and within 24 hours we had 96F. This does not and will not warm the water (here anyway) from top to bottom. It will only really warm it up right up to about 4 inches off the bottom. this was no probelm because once we got in, started moving the water around, the temperature only dropped about 2 degrees.It is bubble wrap but was well worth the $$$ and defiantly a clever idea!
