Powerlix Sleeping Mat Pad 28 x 77 inches

Initially I was excited by the appearance and quality of the self-inflating foam sleeping pad. When I received it, I followed instructions to unroll it and allow the foam to expand, puff a little air into it and close the valves. I laid on it for about 1 minute and thought, “oh, this will be perfect.” Fast forward 1 month to my much anticipated camping trip. The sleeping pad inflated nicely prior to bedtime. Within 30 minutes, the pad had gone completely flat. I re-inflated, careful to close the valves tightly. Same thing happened. All air escaped from some small leak and I was back on hard ground. Sadly, Amazon will not allow a return because It is 6 days past the return window. I’ve contacted the manufacturer hoping that they will honor their “100% Return/Replacement” statement. I’d like to think that they make a good product and that I just got a lemon. I’ll update this review after I hear from their customer service.**Update: Customer Service Nightmare. Initial contact seemed like they were going to honor their guarantee, but then.... crickets. Nada. Zero. Radio silence. I finally gave up. Begged for help from Amazon and they granted me a partial refund. Better than nothing.
