Does it keep the food warm or hot? & for how many hours?

Well this has not insulation, it's a thin layer of stainless steel. If you put this in a cooler the food will stay cold. I use it for salads and no hot food.

The product is not designed to perform the function of a vacuum flask (thermos). There is no insulating space or material. The seal of the larger container is not airtight / leak-proof. The seal for the smaller container is better, but you should not rely on it. I would not rely on this product to keep food warm / hot / cool / cold.

No. It's not insulated, and it's not a leak-proof seal, so it does not maintain temperature. I've found it great for sandwiches and salad (with dressing packed separately).

Negative. It's not meant as a preservation unit as it does not have insulated siding. You CAN put hot or cold food in it though as it's stainless steel and safe for that, but it won't keep the temp hot or cold. Sorry :/

I've used it for hot lunches quite a few times. It doesn't stay boiling hot for hours, but the food is definitely quite warm three or four hours later. I'm really pleased with this Klean Kanteen--easy to use, holds a meal, and very easy to clean. I even put the lid in the top rack of the dishwasher.

As recommended I put boiling water in the thermos for a few minutes before putting the hot food in to heat up the thermos and then yes, the food stays warm for four hours. Not piping hot as it was when first put in, but still heated. The wide mouth makes it really easy to eat from too.

Haven't timed it but longer than any other thermos I've had in the past. If I fill it up in the morning before 7 AM it is still warm (I wouldn't say piping hot) after 6 PM.

If the food is super hot it will keep it warm for that long. Also the cup should be washed in boiling water and kept in a dry place.

No. It might keep it warm for an hour or so. But not for a long period of time.

That would depend a lot on the temperature you heated it too, and the ambient temperature of the room or affected area. Mine usually stays hot to warm for about 30 minutes

It's more of a plate warmer than a plate heater. It's warm / not hot. But it stays warm for a good 20-30 minutes. It's not as good as an electric warmer / heater but it's more "portable" and doesn't need to be plugged in. For what it's worth, I'm happy with mine and I use it regularly to help keep food warm (especially meat).

I put soup in it in the morning, about 8 or so, after putting boiling water like it says andit is warm, not hot, at lunch time, about 12 or 12:30. It's not cold, but not hot, just warm.I like the lunch box and use it all the time!

The Magma Hot Plate heat retention depends on the type of plate/container placed on the pad as well as the food being kept warm. Overall I have been happy with its performance. I use it mainly for buffet-type serving of hot cheesy dips. The food stays warm for at least thirty minutes unless I reheat the Magma to increase the time.

I bought this for my parents. They say their food stays hot 20-30 minutes depending on the plate used, they use polishstone ware plates which is very heavy & they say about 20 minutes. They do heat in a little longer than the directions says. Hope this helps.

It does keep the food cold for a few hours, and it does not need to touch the food. I usually put together my son's and husband's lunches around 7:30am and they are still cold at lunchtime (11:00am and 11:30am). I am not sure how cold food will stay longer than 4 hours though.

It does keep your food warm for a good hour or two depending on how hot the food is when you put it in the Bentgo. But I have found that if you put the Bentgo in an insulated bag, it stays warm for 4 hours.

I would say no more than 6 hours. I packed this for my husband's lunch once.. warmed up the containers with boiling water, as directed, then placed hot foods in it (aruond 7am)... he said it was just "warm" enough to eat at lunch time (12/1pm) but not hot.

This was bought as a replacement for unit in Pyrex container hot-cold container. For foods right out of the oven, it usually keeps food warm for about 4 hours. The hot pack is an odd size, 9x12, for kids lunchbox, though.

Soup and stews stay hot for a long time. I leave to work at 5:30am and have lunch around 1, and it is always hot. When it comes to food that is not liquid or in sauce, like baked fish and veg, it is still warm 7-8 hours later, but not as much as soup and liquids which stay very hot for hours.
