the rice cooker initially work great , but after about 20 usage it start to go from cook to warm prematurely so the rice be not fully cook . it do not happen all the time once every 4-5 usage . the reason I bring this be to cook rice so I do not have to be around to watch it . be not a rice cooker suppose to cook rice automatically ? I do not know if I be the only one who be have this problem .
