I just received my Chili pad and was skeptical. I just didn’t think that it was going to work as well as it said it would. To my surprise; I turned on the pad about a 1/2 hour before going to bed and jumped into bed. My first thought was: wow nice and cool – but will it last. The next thing that I remember is awaking at 6:00 am. Again to my surprise the bed was cool, but I was not cold – it was the best nights sleep that I have gotten in the summer time in years!
