I know this was developed to keep things warm--but can this keep things cold? Can this be used as insulation for lunch bag?

Keeping things hot is the sames as keeping them cold. Think about it, you have a cold side (cold reservoir) and hot side (hot reservoir), The insulator impedes the flow of energy from the hot side to the cold. Thus the hot side remains hot and the cold side remains cold. So keeping warm or cold is just a mater of perspective (which side you are looking at). If you use the insulator as a jacket, you keep yourself hot and the environment cold. If you use for a lunch bag, it keeps the inside cold and the outside hot.

Yes, you can use it to keep things warm. It has an infinite control that goes to very low heat.

No. It might keep it warm?? If you melt it before you put it in the device.

I use cold packs in the lunch bag with the Lunch bot and it stays very cold. My kids have loved them.

I guess you could, but once you remove the ice cubes to put your food inside, i am sure it will lose it coolness regardless within several hours. The bag is meant to be frozen by folding it up without placing any contents in it. For me any insulated lunch pack will work just as well with a ice pack. What I do is the night before I place a bottle of water in the freezer, about 3/4 of the way full as use that as my ice pack, and then when it melts I have a nice cold drink of water, the alternative is much cheaper than this bag.

Very minimal insulation. I'd look at something different for hot drinks. I never tried hot drinks but it didnt keep cold ones very cold. It seems like nothing more than a big plastic container for liquids.

I have not tried for cold for hot it is ok. It comes with ice pack though. It is more of a storage bag than a insulator but I would recommend it

Good question. Unfortunately I have never used it for hot items. Sorry I could not be of more help. Great for keeping things cold.

Yes, the lunchbag is insulated, but it is not as thick insulation as some other bags. However, I bought this set for my son, and I love it. It's a well-made set and it was definitely worth the money.

No. It is not insutated so it does not keep food hot or cold. However, if you put it in an insulated bag, that would help to get you to lunch time. I put a freeze/ice pack in the insulated bag and it stays very cold because the metal transfers the cold. I love my lunchbots and they hold up very well.

I have never used them to keep something warm. I only use them to carry my water bottle around. Sorry!

I don't use it for hot food, I use a cold pack. I would say it is not insulated so I don't think it would keep hot very long at all.

It is not like a Thermos. It plugs in and warms up food. It will keep it warm as long as you keep it plugged in. This item will not keep anything cold.

I haven't done that because I have a fridge at work to keep my lunch cool. I would probably try using those ice packs to keep your stuff cool versus ice...I have used them before and it keeps my stuff cool all day.

It is insulated but I'd have hot lunches in a thermos container of some sort. This is a rather large lunch back. Look at the measurements. If you had hot items in a regular tupperware container, I'd think it'd only stay warm a short amount of time. I used this bag for my 3rd grader and she took soup a lot but I had put her hot items in one of these: THERMOS FOOGO Vacuum Insulated Stainless Steel 10-Ounce Food Jar, Blue/Yellow

This isn't an insulated container - it's just metal. I don't think it will keep your kids' food warm, and I also think the size is a little small for a child's lunch. This might be OK if you are trying to keep food cold if you use it with an ice pack.I have some Thermos-brand containers that keep food hot for multiple hours for my children's lunches. They have a Thermos 10-ounce food container that keeps food hot for 5 hours, though there are many other brands. I would definitely look for an insulated container that's meant to keep food warm.

Sorry, I have not tried that. I put sandwiches and fruit in it and those stay cold.
