I purchased the ChiliPad™ from you for menopausal relieve. I went from 2-3 hours of sleep per night to 8 or more hours of nightly sleep after identifying my “ideal” temperature point with help of your device. The set-up took 5 minutes and the device is very easy to use. I also purchased a water-safe mattress cover to protect the mattress from any moisture. However, thus far, there has not been any detectable moisture from using the ChiliPad™. Since I have only owned the item for less than a month I cannot make any statement about the long term quality of your workmanship. But, so far, so good. Big thumbs up! My life has changed for the better.
