Year 3 used the previous model YZ-20CE, burned out. It was also noisy, but this new one is even noisier and some other tinkling-creaking is heard. I put a three for the lack of progress. Could improve the cooling for silence, put a bigger fan for example. Different pros: Fast, powerful, probably like all induction. Looks good. Management is convenient. Nothing sticks to it, what spilled is washed off with a rag. Different cons: Very noisy, almost like an electric kettle. At low power, it does not reduce power, but it works intermittently, it is difficult to adapt, the brew sometimes escapes.
