Is the Dash Mini Rice Cooker Worth It?

Every rice cooker, mini or full-size, runs on the same simple trick: water boils at a fixed temperature, and as long as there's still water in the pot, the temperature can't climb past that point. Once the rice has soaked up all the water, the pot's temperature spikes, and a thermostat inside detects that spike and flips the switch from cook to warm. That's the entire mechanism, and it only works cleanly if the ratio of rice to water and the size of the pot actually match what you're cooking. Scale a big cooker down to one cup of rice and the physics gets unreliable, which is why you get scorched bottoms or mush. Shrink the whole cooker to a 2-cup capacity instead, and the same thermostat trick works reliably at single-serving scale: one cup of uncooked rice in, the ceramic nonstick pot doing the work, the indicator light telling you when it's done, then keep warm holding it fluffy. The same logic handles oatmeal and quinoa too, since it's really just detecting 'no more free water,' not judging what the water happened to be cooking.
