the chart in your pictures shows 4 levels. Best-Better-Good-Poor. None of these says keeps hot for 12 hrs and cold for 24 hrs like your description.??

Keeps my kids milk cold when they go to school. Not sure on exactly how long it keeps warm or cold.

I can't answer about a chart and I'm commenting as a buyer/user, It is the best for keeping my cold drinks cold with ice lasting for sure all day and well into the nite if the cap is in place, the screw in cap. I'd say 15 to 18 hrs, I've never actually timed it. The ice is the ice from my freezer. I take it to work so I'm in a temp regulated building. Last way less time if I leave it in a hot car on a hot day. I have no idea about a hot beverage, did not try it.

That's going to depend on how you're using them. We used them to warm up baby bottles, ~4oz of very cold liquid, in a zippered insulated bag, took maybe 5-10 min to reach a warm, drinkable temp. If we left the warmer in the bag afterwards, it would still be noticeably warm upwards of an hour later (but not hot enough to completely warm up another bottle by then). Anything you can do to keep the heat contained will improve the longevity.

Yes, 60C is the equivalent to 140F. No, it will not last 24Hr on a single fill.

No idea. Just shows there are 5 levels of temperature and maximum 30 minutes setting adjustable every 5 min.

Hi Dustin...it keeps it hot, just as hot as it went in....my daughter hasn't had anything in it for more than six hours at a time but it either remains very hot or very cold....so far no complaints....

Not sure exactly, we have six people in our house so usually doesn't last long. I know its still hot after 3-4 hours.

I use mine as soup...although both of mine don't seam to stay hot for long...Im sure its cause of the elements im in but I would think it would stay hot longer....I put boiling hot soup in it at around 645am and have to make sure I eat it before noon...but never really get lunch till after 2...it does not work as good as my coffee thermos

I have had it stay super hot for a minimum of 6 hours. It then stayed like warm for another 2-3. Remember to keep the top slid over to closed. Keeps it hot longer. I use these every single day and we have minus temperatures 6 months of the year. Love them and will order again when needed. Hope this reps!

i think it's just the different on the outside. They are both the same for the internal materials. I mostly use my mug for hot stuffs and it stays hot for the whole day. Sometime, i forgot to clean it at night, the next day, the drink is still warm. It kept my drink hot for a longgggg time. For cold drink, it did a good job too, but i read from somewhere that we shouldn't leave ice in there for too long. I'm not sure why.

I would assume its because this cup is smaller. We have both, though, and I don't honestly think drinks stay cold for 10 hours anyway.

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.

It depends also on how much you have in it and how hot/cold the liquid is. Fuller it stays hot longer. I don't usually have it full. I'd say the 4 to 6 hour range works for me. I'm also satisfied with it.

The numbers indicate the temp of the heating unit,,,the higher number (3) heats the fastest and the lower numbers in a more leisurely time.Suggest you use the lower, as you may have to cool it down more often at '3', not something to do if you are breast feeding/pumping and having to open another container, waste some of the over-heated milk to make room for the cooler milk. Or you could run the bottle under cold water for a period of time...so it is all about time...spend it now or spend it later.

The amount of time can vary depending on how cold it is outside. My tea is normally pretty warm evening I am outside for 45 minutes, so it does keep things warm for a while. However, it wasn't made to keep things warm and a thermos would be better for the job. Hope this helps.

The description says it is rated for below zero. 24 Degrees was the coldest I've used it. Nice and warm all night even at 24.

I didn't keep, as it did not arrive by the time I needed it, so I am afraid I cannot be of help on this. But from my research, I believe it is meant for cold not hot.

Do you mean, what are the 3 temperatures? They are low, medium, high. I have never used high as medium is quite warm enough. Hope this helped you.
