I read many reviews before choosing a food jar. Many were cheaper and some were more expensive. I fill my jar with boiling water the night before and after heating my lunch the next morning I empty the water and fill the food jar with the food (so far soups, chili, pasta, beef stew). I usually eat my lunch about 8-10 hours later and it is always to hot to eat:) I usually have to let it cool or blow on it, but I like my food hot so it is fine with me. It is by far the best food jar I have ever used. It seems to be durable and the handle keeps it from rolling around in my jeep.
