Didn't last 12 hours
The product stayed warm for way less than 12 hours but I suspect this is because it was very cold when I used it. It probably lsdts longer in warmer weather but I don't need one in warm weather. For the time it lasted, however, it worked well. It should really say it lasts for UP TO 12 hours rather than IT DOES last for 12 hours.
