Which brand of electric pressure cooker is better?

My own personal experience-Zhongke Electric. I bought a mechanical version for my mother. Since it was put into use in 2006, it has been working normally. I bought an electronic version myself, and I haven't had any problems since 2009. I use Zhongke electric pressure cooker ok, because I have never used other brands, so I have no chance to compare with other brands. Dare not talk nonsense
