4'x4' Durable Air Pillow For Aboveground Swimming Pool Winter Cover

Threes pillow sent was not the same as the one pictired. Picture shows a round ball, i received a 4x4 pillow. I'll give it a try anyways.

Works good

When I purchased the pillow, the image was of the round ball configuration. I recieved the square configuration. Time was not on my side,was disappointed, but I used it.
