I have used them all. I didn't have as much trouble as you when I bought it. I bought a bear first, and its function is quite general. I regretted it and gave it away. I wanted to buy a Jiuyang one, but later I bought a rice cooker of Sky Electric by mistake. It looked good when I first bought it. Bibel's is much better. You can make an appointment, put things away before going to bed at night, calculate a time, and set it before the next day.
