Query: Not really worth the money.

I hate giving poor reviews, but this thermos leaves alot to be desired. The first thing that I hate about it, is trying to clean it. There is a coil on the inside that collects the food that is being warmed. As the thermos warms the food, the food around the coil burns and cakes on the coil. Trying to wash this thermos is a nightmare. Water seeps in between the outer container and the inner container, leaving dirty, soapy water that doesn't shake out easily. I finally threw ours away, because it wasn't worth the time and effort.
