Do not buy!! This thing is paper thin. I've always used 12 mil covers, and this is no where near the thickness of my old cover. No where on the packaging does it even say it's 12 mil. I've had this thing on the pool in 100 degree weather for the whole month of August. Took it off and the pool is icy cold. Our old cover had to be removed every couple days because the pool would get too hot. Supposed to have a 5 year guarantee, but I doubt it will even last a year. It comes from Leslie Pool, so it's just another of their over priced rip-offs. Run, run, run away from this product!!!!!UPDATE: Only 5 weeks after purchase a 6x6 inch area near the seam is already falling apart. I contacted Blue Wave, but they will only honor the guarantee if I give them another $58. $200 bucks for a cover that only lasted 5 weeks. Total rip-off.
