This electric heater can be used at two different temperatures. It's always comfortable with a warm high-temperature surface (approx. 39°C) and a gentle low-temperature surface (approx. 32°C). It can be attached to a circle or other structure with convenient fixing holes. A metal tube is used to prevent mischief. The warm fleece cover is hand-washable, and the main body can be wiped clean, so it's always sanitary. Energy-saving design for daily use. I'm selling this because I bought a larger version. Used for about six months.
