am thrilled. Have bought the Thermo food container by Esbit, because I like a hot breakfast to the office take. My experience when I einfülle the container with hot porridge for example od. Quinoa to 6 hours early, then breakfast is very hot even at 9.30 / 10 h. If you fill in the morning a hot soup for lunch in the office a, we must also be careful that you do not burn yourself. A suggestion for the manufacturer would be that it makes the insulated containers ev with a larger feed opening and the entire container width -. I eat my breakfast directly from the food container -, then this food container would be more suitable for the ride from Essen.
