How long does the food stay cool or hot ?

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.

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

I have not tested it long term-just to transport an already hot pot to a dinner and serve directly. I had another insulated bag which this one is replacing due to some unfortunate damage (unrelated to the crockpot) that kept food nice and hot for at least an hour. This one seems a bit thinner, so I am thinking at least 30 minutes? It does fit nice and snugly to the appliance so I would expect it to retain heat reasonably well.

it depends how hot you want it. I put mine for about 2 minutes and it lasts about 15 minutes. but then it cools and you redo it.

It takes a meal about 40 minutes to heat up. I like it because I spend most of my time in my pickup and often out in no man's land. It's nice to have a hot meal in the cold weather.

My experience is that cooling for about 15 minutes works best. Hot cakes tend to "tear up".

If you mean hot, a couple of hours. Life of the pack is dependent on how many times you heat it up.

Agree with many other responders -- stays warm for maybe 8 hours -- but definitely not hot after that. Insulation is present, but it's not like a thermos at all.

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

No, it stays cool because of the air! If it does get warm, just let the air out and put fresh cool air in.it, takes just 2 mins.

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.

Hello, this was a gift; however, the recipient told me he can put hot food in it and it's still very warm at lunch. The recipient leaves for work at 5:30 a.m. and has lunch at 11:00. I would feel confident saying that your food would be edible for 7 hours. Hope this helps! He is very happy with this product.

After placing prepared heat packs in both top and bottom sections of the carrier, I put 9x13 Pyrex dish in top section and the food stayed hot for 4 hours! When I have used only one heat pack, the food has kept hot for at least 3 hours.

I don't have a definate answer. It would depend on how hot the food was that to begin and how well it was insulated. We use ours in the insulated Pyrex containers immediately out of the oven. We usually serve the food within 3 to 4 hrs and it has been just about the correct temperature. I would think if the insulation was good it could at least be very warm. Very few other alternatives out there. This about as good as it gets besides bringing your own stove.

It keeps it hot for 8-10 hours and warm for up to about 14 hours. I found that it helps to warm the thermos up with hot water before putting in your hot item.

After 7 hours my lunch is very warm, but not hot. (I have found that after 7 hours, food in my soup Thermos is still quite hot.) I understand that the Ms Bento is supposed to keep food hot for 6 hours, when used as directed.

When I have used my hot packs, they have kept the food hot to warm for several hours say maybe 5 hours or so. Depends a lot on if the package is opened a lot. The more it is opened the less time it will stay hot. The person who said the hot pack is HOT when taken from the microwave it correct. But if left in the container, it should be okay for a child to touch by lunchtime.

Similar weather to where I am. It will get cool in about 2 hrs. If the drinks are cold going into unit they will lose some coolness within first hour then be maintained at that temperature until around 2 hrs when they start to really cool down. Long trips or short stops will keep it all KOOL
