16 years of work. After the refrigerator was designed, I have always wanted to design products for young people's real needs, but the analysis skills and methods are not yet mature, so I can only judge subjectively (this is why I don't do middle-aged and elderly people and children, and I can't empathize with them). Then, according to the feedback from myself and about 10 people around me, I made this microwave oven. The actual appearance is nothing to see. I just want to operate in a simpler way. At present, household appliances are all using many functions, but in fact there are only a few functions. The use of this millet product feels really close to young people.
