It doesn't get hot. If you leave it on for awhile it will get warm but it works without heat.

It's not really insulated, I would say it could keep it warm for 30 minutes to an hour maybe.

My first response would be yes but always be sure that it doesn't get too warm.The heat may even irritate the area.

Yes. As someone already mentioned, the loss of heat through the exterior wall indicates a serious insulation issue. It can't keep anything hot if the heat is escaping.

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.

Yes it keeps it hot if you can get the lid to screw on. You will need a lot of patience.

As long as you can keep it stable-- it gets very hot and could start a fire!

The thermostat will keep the temp. In a safe range. Leaving the unit running to long could cause over heating.

Yes, but it really does not get hot. It is the only feature that isn't 100% great. I personally don't mind that it does not get hot.

Yes, it is because it won't overheat and it is easier to hold and move around without your arms getting tired. You have to keep it moving though, even on low it gets hot.

I find that it is a warm blanket even without using the heat elements. I believe it is designed to retain that heat. I don't believe it makes you to hot, but it is a good blanket with or without the heating function...

It could handle heating, but not a great way transport. It may leak a little around vent with straight liquid.

Yes, it can. It doesn't keep things warm as long as it keeps them cold though. I'm pretty sure that's normal for thermos type stuff though.

Yes, one of the nice points to this is that you can indeed store both hot and cold food items without causing an issue for either. Hot stays hot. Cold stays cold. It's a great product.
