with If there is hot water/formula in the bottle does the outside get hot as well?

I have both bottles the thermal and not thermal. The thermal ones don't get hot or cold on the outside they're amazing at keeping milk cold. You can feel the temperature of the liquid on the bottles that aren't thermal - I love it because I couldn't tell with the plastic ones I used what the actual temperature of the milk was, so I always had to test it. With these bottles, you can tell right away so if it's too hot, you'll know, it's a great safety feature actually. I also like that the non thermal bottles heat up so quickly, much faster than glass or plastic bottles. I just run mine under hot tap water for about 30s. Hope this helps!

Yes, same temperature as the liquid inside. So, be careful when you pour the very hot water inside the bottle.

Don't get it. The bottle gets so hot you can't touch it and cools down faster than a regular plastic bottle. It leaks also. It says thermal, but the one shipped to me was not. I'll ship you mine for free!

I didn't see that. I use mine with glass bottles. It heats the formula up really quick. Just be careful of the hot glass and you have to play around with the timing on how fast it heats the liquid because it's much faster then a plastic bottle. I only use glass bottles now with it at night because it works so quickly and I don't want to listen to a screaming baby for 2 minutes with a plastic bottle when a glass one heats in a minute or less! But again, play around with it if you do choose to use a glass bottle so you don't BURN YOURSELF OR BABY.

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.

Yes, but not too hot. We have refilled ours with hot water when the children were cold and wanted a longer shower after playing in the ice cold rivers.

Of course!! Put the bottle in a pan of warm water until it is as warm as you like.

Absolutely. Even when it's at full boil (after adding fresh water or hitting re-boil), it's only slightly warm on the outside. You do need to be careful when opening the top, however, to keep your arm away from the opening.

It does but takes up the full space leaving little air in between bottle and warmer so it heats really fast and really hot. Have to check it carefully.

The outside becomes warm but not hot like the stainless steel outsides will do.

Nope! I've used mine without turning it off, or taking breaks, for well over an hour and haven't felt it get hot yet.

No it doesn't get hot. But you should read specs. It would take you 3 days to fill your tub. Read specs carefully it has specific applications.

No, it only generate wind when it runs. But it base on the surroundings. If weat her is hot, I'm not sure whether it will create heat.

I have occasionally noticed a little "sweating", but never an issue with handling the bottle. Might be different in a more humid climate.

Yes, the exterior does get hot during use - including the top. It works like a regular waffle iron.

I don't think it would make a difference if it was breast milk or formula. But honestly I think this is a waste of money, it takes way too long to heat up, it would be quicker to hold bottle under hot running water! I regretted this purchase.

yes, depending on HOW hot you are talking about. does not get hot to a temperature that is the least uncomfortable to the touch; it is hot air blowing out through a plastic tubing...

Yes, that is normal. The hot liquid inside will warm the air between the inner and outer layer. The warm air will warm the outer layer of the bottle and you will feel it. That is how it insulates and keeps your hot liquid hot for up to 12 hours.

Yes. I used our bottle warmer with the bottles all the time, but I did reduce the time because stainless conducts heat more quickly than glass or plastic. Also, in a pinch, you can run hot water over the bottle, shake it, and have lukewarm milk/formula.
