At first I was unsure about the ChiliPad™, but fortunately I purchased one. From the first night I realized that it was a fantastic product. I slept all night for the first time since I can remember. The constant cooling is unbelievably comfortable, and has improved my sleep consistently. It has solved the problem of my wife nit liking it as cool as I like it. We can now keep the bedroom at 72 degrees and I am comfortably sleeping, thanks to the chilipad. My wife says that I hardly snore since using the ChiliPad™.
