It is described that the outside does not get warm when holding hot liquids - have a stainless mug which does (no vacuum?).

The outside of the thermos does not get warm at all. Under the cover is a screwed on bottom of the lid. You have to make sure that that is tight or it could leak. You also have to make sure you put the lid on with the lid open and not closed because the vacuum gets so tight that I am unable to get it off. This thermos is excellent. It actually keeps hot liquids whether it be coffee, broth, or tea hot all day long.

If the outside gets warm or hot with hot liquids (mine doesn't) there is no insulation, therefore no vacuum.

when I've had hot liquids in it, the outside will get a little warm but its not really noticeable. Never had any kind of issue or thought about it until Amazon sent me this question.

You know, I was thinking about the pot handle, not the lid handle. Pot handle definitely does NOT get hot. Will try to boil something tonight and get back to you regarding the LID!

It really depends on how hot your water is. If you use boiling water (not really recommended for most teas if you don't want it bitter) then the glass will get uncomfortably hot to hold (not leave actual burns, just uncomfortable to hold). I found that the outside only remains uncomfortably hot for a short time if you use really hot water. If you plan on filling it with boiling water and then heading out the door, you might want to purchase some sort of a sleeve for it.

Its not very hot at first. Hot but not very hot. The coffee will cool quick when poured into a cold mug.

The coffee is hot when made. Then, due to the laws of thermal dynamics, it slowly cools to an equilibrium between the coffee and the outside environment the insulated pot is in. There is no button to press that can counter these basic laws of physics.

I wouldn't put anything hot in it even though it's double walled the heat of the coffee or cocoa could make it uncomfortable to handle. I feel that the glass and straw could hold up to the heat.

In answer to your question, I just filled a bowl with water and and microwave'd it until the water was boiling. The rim stayed cool enough to pick it up comfortably, but the lower part of the bowl was pretty hot.I do not have the mugs anymore to test, I passed them on to a friend who can use them more than me :-)

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.

Nope, like others have posted, the rim stays very cool compared to the hot liquid in the body of the mug.

I'm sorry, I haven't even tried the mug yet, so I'm not sure about hot beverages in this mug.

It's not for hot beverages, only cold. It either says that on the insert flyer or on the bottle.

The coffee stays hot only about 1/2 hour. It is double walled stainless with no insulation.

It doesn't get warm at all. Putting drinks in the rocks, it glows all the way through the glass and doesn't heat it at all or melt the ice.

The cup gets hot, not as much as a ceramic cup, though. And the handle doesn't get hot at all.

This gets hot enough to touch but doesnt heat my mug well. I would not put a plastic tumbler on it, it will melt it for sure.

I own several of these and I can feel warmth with my coffee (not hot just that it is warm) and just filled my 32oz. with ice water and it is cool on the outside, that doesn't change the fact that it holds the temps whether it is hot or cold. I haven't heard of the bottles being defective.

It's not hot at all. I was also concerned about contact with paper, but the heating element is inside the kettle, not on the hotplate.
