They are all about the same quality. You said Hemisphere, besides low-end products, he also made many low-end things, which used to be Hemisphere rice cookers. The quality is very good. In addition, because rice cookers always have no complicated circuits, it is good to choose cheap ones. I recommend a hemispherical one, because my family has lost it for more than ten years and has not changed it. Finally, change until the coating falls off.
