The old microwave oven only has two rotating buttons, one is firepower and the other is time, which is simple and clear, and the old people can easily operate it. Moreover, there are no problems such as splashing, and it is easy to clean with a wet cloth. However, it has fewer functions and fewer options.
The new microwave oven is controlled by microcomputer and can be intelligently controlled by APP. It has many functions, but it is not very convenient for beginners to operate. You need to follow the instructions step by step, which takes time.
