I buy these to put in shelters for community cats. Our winters can be brutal. I place a blanket with this warmer in the middle of it, so they do not get burned, and it provides warmth and comfort to these outside fur babies. I get the 18 hours ones and feel they make it through the night and into the morning with warmth. I have found that re-shaking them and playing with them for awhile will a lot of times reactivate the warmers for additional time and heat. I was throwing them out once they cooled and quite by accident found this brings heat into them, once again. So I do get 18 plus hours out of most of them. Would not be without them in the winter months.
