The quality of the hemisphere is very poor, and the temperature inside the microwave oven is very high, but the circuit board inside it is not resistant to high temperature. I bought the 300 yuan for two years, and it is always broken, repaired or broken. When the temperature is high, the program will be disordered. It is still recommended to buy an induction cooker, which won't have such a high temperature. Also, the plastic panel on the edge of it always cracks. I used my brother and sister to touch it several times, but it still doesn't work, and it is not resistant to high temperature. I have no confidence in the hemisphere now. The soymilk machine and hot water kettle I bought also broke down in less than a year.
