Fresh and hot water at any time. Easy to use. Silent device. I bought this product because I have long dreamed of a water fountain but without the hassle of bottles. Or in my office I have no water supply and replace this fountain so practice my water bottle and my coffee. It is a well finished product and the large filter allows to forget fleet chore for several months. The only negative is that you keep the water cooler away from direct daylight so avoid the sun on the water. to advise Fountain at Bio Bottle Filtrante Re-mineralizing Icebergfilters Cold Hot
