The Hole Warmer Ultimate Edition is our most recommended heating stand for your masturbators- a stand type heating rod created by upgrading many elements of the USB stick type heater, which has also been a popular model in our store. The biggest change is the heating system. It heats up rapidly for the first 8 and a half minutes; after that, the built-in thermostat keeps it at human body temperature. On top of that, it turns off automatically after one hour. Comprised with one of the most advanced temperature-controlling features throughout all toy heaters!
