How long the cold foods stay cold and hot foods stay hot?

As long as you prep the comtainer with either hot or cold water the food stays at temperature for around four hours.

Not real sure, as it was eaten before it got cold. It is heated thoroughly and I can only guess, perhaps 20 to 25 minutes.

It defintely keeps the food hot for at least six hours. My only complaint is you can microwave using it.

I didn't remove the food from the inner metal cylinder so my food stayed warm for about 3 hours. I left the inner part inside the base because I didn't have pot holders to remove it at work and it gets hot. I don't know how long it would stay warm if you unplugged it and left the lid closed.

I cannot answer a specific temperature. But I can say anecdotally that hot food from the oven or stovetop will stay very hot & even possibly simmering (in a shallow pan) when placed directly onto the heated surface and covered w/ a lid and towels. And food out of the fridge will take quite a few hours (4-5) but will eventually become hot enough to burn your tongue (especially stews or items w/ more liquid).

The removable food container is not designed to keep food cool. Food should remain refrigerated until you are ready to begin reheating it with the Lunch Warmer.

Not as long at you'd think. I put refrigerator-cool leftovers in the crockpot when I leave for work in the morning, and by lunchtime it only takes about fifteen minutes to be piping hot and ready to eat.

Use hot water in lower container to keep food warm. Use ice water in lower container to keep food cold. Obviously, if you want to keep food cold, you don't use the burners.

They only stay hot or rather just warm as long as the food is really hot. They cool down very quickly to room temperature once they are out of the microwave oven.

You can do both, hot or cold. Cold for sliced fruit or warm for rolls. I stick it in the freezer for about 15 minutes, but you could leave it in the refrigerator for awhile as well. For warming, I use my InstaHot tap to put boiling water in it for a few minutes and then dry for a nice warm. You could probably use the hot tap water as well.

I would estimate that it keeps it cold for about 3-4 hours. And no, the ice pack doesn't have to touch the food.

It depends how warm the environment is, how much food you'll have and how many ice packs you'll use. The more you use, the more likely the food will stay cold/frozen.

put ice packs in mine. it is cold 9 to 10 hours later. If you preheat the thermos it will go just about 24 hours

In my experience by pre-heating the container with boiling water first, it keeps food hot 4 to 6 hours. By chilling the container in the freezer and layering in some ice cubes I have keep ice cream hard 4 to 6 hours, and soft but still solid over night.

I have not tried hot food, but my guess would be that it stay warm, not hot without a hot pad.

By "hot" I mean it is too hot to drink without burning my mouth (at first), and a few hours later it means too hot to drink without masochistic discomfort. Don't know about cold - haven't tried. WHOOPS! I thought you were asking about the Thermos bottle I purchased at about the same time. I have not been concerned about the bag's ability to keep items hot or cold. Sorry.

I have not tried frozen goods. A hot food lasted about 2 hours. Still warm not hot.
