First off - just as the name suggests, this is a small rice cooker. I live alone, so I don’t need to make a lot of rice at once. It’s the perfect size for me. I’ve only ever cooked sushi rice in it so I can’t speak to other kinds, but it cooks it evenly and consistently. 

When you plug it in it automatically sets itself to “warm” mode. When the rice is done cooking the button will pop up from “cook” to “warm” so if you don’t unplug it, it stays there. This is fine if you want to keep your rice warm while you prepare other food or whatnot, but just remember that if you don’t unplug it it will never turn off. That’s why I took off a star.
