Will it insulate/be functional for heated beverages? If so, for how long?

http://polarbottle.com/ Click FAQS link for the following info: The Polar Bottle Thermaluxe performs the best for hot liquids. According to our tests, in a standard mug, water at a rolling boil (201F) at 5,430 feet above sea level will drop to a temperature of 118F in about a half an hour. In the Thermaluxe, on the other hand, the water took five and half hours to drop to 116F - an impressive 11 times longer than a standard mug. Hope this helps. Cheers!

Didn't try it with hot beverages, but it doesn't keep things cold very long.

Won't be too hot to drink, but well enough as a hot drink. Even you place simple cold water on it, it will turn to warm temperature.

Yes...it will handle tea, coffee, etc as long as it's not 'boiling'. I think the plastic will take it, it just get more rubbery/flexible. Regular warm drinks are fine. Obviously, you can't heat anything in it. We bought as requirement of Girl-Scouts, but I'd personally prefer to use military surplus or porcelain coated steel which are far more utilitarian (but indeed heavier).

Hot??, that's subjective. If unopened it would keep hot liquid fairly warm. Best you can expect, subject to outside temperature

No this is not insulated per se. It may keep it warm for a little bit, but i use a thermos instead for things that need to be kept warm.

I have only used mine for cold drinks and they do a decent job of that in summer weather. I would have to guess they would work equally well with bottles of warm liquids for a period of time also. They aren't double walled like some containers you can buy else where and generally do keep hot/warm liquids warmer for a longer period of time.

I don't believe so. It's a relatively light mug which is great for travel and it does do a good job as a heat capacitor for a good while. I've had drinks stay hot up to an hour. Depends on the environment. A great mug regardless.

I've never used this for hot beverages but it does keep things cold for at least 16 hours.

You can put hot liquids in it. But it isn't insulated. You may want to look at the wide mouth version.

This is simply a large insulated thermos. No heating element or electrics. It will keep your already heated or cooled beverages warm or cold for about 4 hours. Super convenient.

I seriously doubt that it will last that long. A few hours is the most I'd use it to keep food cold or hot.

It has a rotating spout that you could drink from. I wouldn't advise it for hot drinks as it keeps them at such a high temp. No problem with cold.

The cup would hold hot beverages just fine, but copper is a great conductor of both cold and heat. I just put some HOT water in a mug and within 30 seconds the cup as well as the handle became too hot to hold. If you were to wear an oven mitt while drinking your hot tea or coffee you should be just fine, but for bare handed use I would not advise it!

Not at all. I've had this mug for about 4 months now, and it's been nothing but absolutely great. If you put hot stuff in there, you can expect it to stay hot, without affecting the temperature of the outside of the bottle. In fact, you can just consider the outside of the bottle to be almost completely isolated from the inside, as the isolation is done extremely well.

The lid is a press - not insulated, but I doubt it would be worthwhile for it to be insulated. This is not a thermos, but a French press that does a pretty good job keeping coffee hot for longer than a glass carafe would. Use a tea cozy or put the coffee in a real thermos if you want long term heat retention. And....it won't break - a real plus.

no, but it might take quite a while. I put water in it and it took about 20 minutes to get what would be just warm. I haven't tested its Temperature-over-time/liquid.I'd do it now because you have me curious about it, but the unit self-destructed within weeks.

Similar weather to where I am. It will get cool in about 2 hrs. If the drinks are cold going into unit they will lose some coolness within first hour then be maintained at that temperature until around 2 hrs when they start to really cool down. Long trips or short stops will keep it all KOOL
