First, this is super nice thermos. One might think that it is small but the battery capacity is what it takes. To keep food hot you have to put boiling water prior to intèrieur and his food (after throwing water !!!). I ca at 7 am and my meal is still hot at noon. Finally a thermos that keeps its promises (I have tried a lot before, with no microwave in my college. The only catch is that the opening is a bit small ... however very practical spoon integrated ... well you have understood me, I highly recommend !!!!
