Very nice solar cover. Not only does it heat the water it keeps a good bit of trash from the trees out of the pool. Yes it only heats the surface but that water mixs with the cold water at the bottom and slowly warms the pool. It will easily heat my pool 5-10 degrees in a few days of direct sun light. Be careful, the water directly under this cover in the sun can be very hot! Keeping this cover on at night helps hold the heat in. Mine came slightly larger than my intex 15' ultra round pool so it had to be cut down. This is very easy to do with scissors. Just have one or two people help hold the cover in place and walk around the pool cutting as you go. BEFORE YOU CUT TO SIZE... make sure you leave it in the sun to get hot and expand. I would also leave it an inch or two bigger so the sides fold up at the edge just a little and that will help keep trash from blowing into the pool around the edges. You may also want to leave a flap to clamp it down above your pool return. My return would push the cover to one side of the pool. I now clamp a flap over the return and the cover stays put now. Overall I'm extremely happy with this cover and at this price I'll buy a new one every year if need be. So far it's holding up well so maybe I'll get a few seasons out of it. See attached photos. P.S Just finished building a solar heater to use with this cover for maximum heating. See photos!
