It's fine without heating. The machine with heating is purely a gimmick. Plastic cups with heating pipes are easy to age, and bisphenol A will be released at high temperature for a long time. The heating pipes will turn yellow after being used for a period of time, which is extremely difficult to clean, and the heating power will reduce the stirring force, so the beating is not fine, which may require filtration, and there are too many disadvantages.
