I am selling this item as I no longer need it after weaning. Purchase date: November 2018 Usage time: Approximately 5 years I've used it for a long time, but I think it's in good condition. I was using it until recently, so it's still usable! Operation has been confirmed, and it has been cleaned with alcohol. *Please understand that this is a used item. I will send the main unit, cord, and instruction manual. I have discarded the box, so I will wrap it in bubble wrap and ship it in a substitute cardboard box. __ Description It has a 6-hour power-saving timer. You can save on electricity costs by stopping the power supply during times when you don't use hot water, such as when you sleep or go out. You can choose from three保温 temperatures: 98°C, 90°C, and 70°C. You can adjust the temperature not only for hot water but also to your preferred temperature, so you can use it for preparing food, etc.
