Thank you for being a SmartTechProducts.com customer. Our Patented, Add-A-Stat orders are increasing quickly. With the Fall Season Beginning, everyone is getting ready. This product is great for this time of year. It turns on, whatever you have it plugged into when the outside approaches freezing. Then turns off when it gets around 40 degrees outside. This helps keep your electrical bill down and limits a little of wear and use on whatever is plugged in.
