We recommend commercial rice cookers for sous-vide cooking, because
Slow cookers, although they can be controlled by SousVideMagic and cooked many good sous-vide dishes, their performance are not as good as rice cookers, because their baths are small, heaters are side wall mounted, thick ceramic pots make stable temperature control very hard to achieve, and not well insulated for efficient heat transfer. But they are cheap and readily available and very good for long term (over four hours) cooking.
The rice cookers we sell are fully tested with SousVideMagic and tuned (PID settings) together for optimal performance.
Most of our rice cookers are of commercial quality and not readily available in some North America regions. They are all priced competitively.
