It works very well. One of the problems with it is you need to buy pans for the inside. Small loaf pans work great. Foil if you can find them. I used metal ones from dollar tree and bent down the edges with a pair of pliers to make them fit and packing a lunch is easy by covering the top of the pan with foil so it's ready for heating. There is a big downfall, there is no way or securely stowing the cord away. It's made to be wrapped around the lunchbox which can become comber some and the tabs for the cord break easily.
