Has anyone ever used a good cup?

You can look at the multifunctional portable drinking cup that is ringing. I'm going out to play on the eleventh. I didn't trust to use the hotel kettle and cup, so I started with this drinking cup and took a fancy to it, because it can not only boil water, but also cook. The boiling of water has two stages, one is normal boiling to 100℃, and the other is heating to 55℃. I usually use mineral water at 55℃. I can drink it as soon as it is boiled without burning my mouth. I have also tried to heat milk with it, which is very fast, and it will heat up in less than 1 minute, which is much more convenient than cooking in a pot. I use it at home. Besides boiling water, it can also be used to cook mung beans and scented tea. People who are usually busy at work can also wash mung beans and pour them in before going to work, just like me. When I got to the office, I added water, turned on the power and chose to cook for 45 minutes, then put it aside. When it's cooked, I can have a mouthful of mung bean soup to clear away heat and fire.
