This heater warms you up instantly, from the core of your body, thanks to the double effect of carbon and far-infrared rays. It's great for the kitchen floor, bathroom, before bed in the bedroom, or under your desk. It quickly warms you from the core, and you can use it economically by switching to low or turning off the heater. I purchased it on Rakuten for about 17,000 yen and have used it for about two months. I haven't used it much because I live in a warm area.
