I am elderly and can not generate enough heat myself to sleep soundly without an electric blanket. My Sunbeam blanket is marvelous! I use the preheat feature and appreciate getting into a bed that is already warm. The blanket keeps me toasty all night so that I can get good restful sleep, and I do not even have to have it on the highest setting. the controls are simple and easy to use. This blanket is an excellent product.
