how do the hot packs heat up?

Microwave them. This is the best shoulder wrap I've found. Everything else slips and slides.

I haven't used it for heat as of yet, but from the instructions, you heat the packs in the microwave.

I only did cold. But if you purchase packs which you can heat (probably microwave) you can insert these into pouches and use..

They get warm but not hot. I would think the worse that might happen is the plastic might yellow after years of being warm.

They are soft so they get re-shaped a bit. I had a few bars stacked up and the did ok. They just get soft in heat.

They don't get hot! There is a very small uncovered metal piece near the actual pan that gets a little warm, but is not in the place you would pick it up! Hope that helps!

They do not get hot. But they do require a transformer which may get hot. I am using them in a kitchen exhaust hood which already had a transformer built in.

yes, you can put hot food on it. You heat the pack in the microwave and then I put it in my carrier. The hot pack and my food stayed warm (not hot) for more than 8 hrs.

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.

That I know of yes. Put the packs in the head piece. Zip it up and then put it in the microwave.

They get hot like a normal plate, but nothing above and beyond that. I reheat leftovers all the time in them and no complaints.

It is so easy! Just put in your packs, fill it with waster to about an inch from the top, plug in and make sure the correct light illuminates, and wait several hours for them to heat up. Once they do, wrap them in towels, relax and ENJOY! It's a very easy machine. Love mine!

If you turn the pan on high heat it will get hot. If you cook at Med or lower temps they do not get hot.

No they don't get hot. I have microwaved these and other shapes and sizes of the same type, and no problems. I think they are realy nice looking and serviceable.

There is a small disk that can barely be seen in the photo, you simply snap the disk and the entire pack will begin to crystallize. That is how it heats, it is a self heating pack. To get them to go back to a liquid state you boil them in water for 15 minutes and you can then use them over and over again.

I didn't try hot things but for cold, you need to have an ice pack in the bag. The insulation lining is there but does not work totally on its own.

they do get warm, but I normally use a pot holder to take dishes out anyway to be on the safe side. I would suggest a pot holder.

Yes, the ones I have are, and then you get the hot/cold packs that further keep your food at the desired temp.

They do heat up inside the case, the bottom where they lock into place is the heating element. There's also no power switch so be sure to unplug after use! The cord just comes out the side and I wrap it around the entire thing when not using, I think it's just not shown in the photo.
