Title: Very good thermos
Review: I used this all year for my Kindergartener. It worked well. I put very hot tap water in it and placed the top on for a minute or so before filling it with food. Then, heated the food 'til it was very hot. That combination of steps resulted in warm food 3 1/2 hours later. I am not sure you have to go through all those steps but it worked for me. Food might have been hot without doing so - but I can't promise.
