I bought two for my Wife, one for home and one for work. She loves it and is going to run a real time test on it right now to get an actual time. She loaned it to a coworker who used it for a week and bought her own but got one with eucalyptus which she didn't like as well. 1,000 Watt microwave, 2 minutes, provided about 20 to 25 minutes of super heat and gradually cools. Helpful?

Most would agree about 20 mins (depending on your microwave and how long you leave it in). Remember though, heat mainly treats symptoms, not the cause. Consider exercises like the ones in Bulletproof Your Shoulder to get at the heart of the problem.

It stays really warm for about 20 minutes, but I have found that if you lay down with it, it will retain some amount of heat for several hours, or longer, during the night.

About 20-25 minutes but it is comforting and reheats without any issue soon after

Heated to a moderate temperature for a minute and a half in a microwave, it keeps the heat for about 10 minutes.

Usually 20 minutes but I have noticed the heat intensifies slighty when used numerous times in a row. That's a good thing :D

Hello-- Yes, I've used it up to nearly 2 hours, but it gets very hot, so be careful.

It does keep the food hot but not sure for how long. At least through a meal.

The water stays hot for approximately 10 minutes; that is, hot enough for a cup of tea or coffee. I'm not sure how long you're looking for, but if you kept the burner on, I'm sure the water would stay hot for much longer. Just remember, when you are done using the kettle, it should be emptied to avoid any rusting on the inside. I love my little kettle...I just wished it whistled.

It stays hot enough to drink for upto 3 hours, but stays fresh tasting, not burnt like coffee makers that have warming plates. It helps if you pre warm the pot with hot water before brewing.

It stays hot until coffee has been in long enough to cool down. Depends on several mitigating circumstances.

I took it camping...filled with near boiling water. It stayed hot/warm for about 4 hours in my sleeping bag.

Yes it keeps it hot if you can get the lid to screw on. You will need a lot of patience.

It stays on for as long as you have it plugged into an outlet. I even plugged it into a timer and had it go on and stay hot for several hours until the timer shut it off.

I pour my coffee around 6am and it stays hot til around 8 or 9 and then stays warm for about 4 more hours. I dont drink it that long but I've left coffee in until after lunch and its still warm. It is the best thing I've bought from amazon. I use it every day. Love it!!!

If you heat it for about 6 minutes, it gets pretty darn hot. It will stay warm for about half an hour.

It will stay hot much longer than it would in a regular ceramic mug, and the outside will stay cool. After 20 minutes or so you might want to microwave it to warm it up.

You can feel the heat escaping from the outside of the cup immediately. The liquid remains hot for maybe 15 - 30 mins depending on the temperature of the liquid when poured.

If you preheat the mug with hot water for a few minutes it will last up to 5 hours hot. If you put it in the freezer for a few minutes it will keep things cold for up to 7 hours as advertised. Be sure and use the open and close valve. This cup has a small bottom to accommodate cup holders in cars. It does tip over easily. I love mine.

I noticed that it stays pretty hot for several hours, I make coffee Sunday for church, make it about 10am and its still hot at 5 when I've had any left, also it doesn't get cold for a long time, 30 seconds in the microwave makes it too hot to drink. I'm real happy with this product.
