These work and stay warm and even better - my husband actually uses them in the winter. My husband is not necessarily a "gizmo" guy - but I had gotten him the hand warmers that run on chemical reaction and stay warm for some time, and he used those. I decided to upgrade him to something more long-lasting. He uses them and he says they keep his fingers from getting frostbite as he does his outside work. He just tucks his hands in his pockets next to these when he realizes his hands are getting too cold. Thank you for a great product.

I bought these for a trip to Iceland. I have previously used hand warmers in packets that you shake to activate, then put the packets in gloves. This product is wonderful! I especially like that I can keep them in my coat pocket and wrap my hands around them without gloves to keep my hands warm. Then when I wanted to take a picture, my hands were already "glove free." This was always a problem the packets inside gloves. I charged them daily but they lasted at least 4-5 hours as other reviewers have stated. They heat up within seconds. I used the lowest setting with bare hands and the medium setting when I wore gloves. You won't be sorry with this product.

These are super warm and powerful. I used them in New York during the winter time and they got really warm even on the lowest setting.

Don't waste money buying overpriced electric hand warmers, these are perfect, get super hot and keep your hands warm. I purchased for my boyfriend who works outside at the airport, he said they really helped and started recommending them to his co-workers. Brought a pair for me since I hate wearing gloves and they're the prefect replacement for that as well. AND The battery lasts his whole shift! Takes a while to charge so we charge them overnight with the rest of our electronics.THE ONLY CON (which doesn't bother me) is the temperature can change a bit rapidly and go from super hot to a little less hot usually when on a level 3 (still my favorite level) but you might have a moment when you have to release them for a bit. I think because of that my boyfriend keeps his on level 2 which also helps reserve his battery and says its the perfect temperature to keep him warm.FYI: You can notice scratches on the champagne colored one easily, I recommend buying a darker color one if that will bother you.

I gave these to my grandson for ice fishing, and he said they work great. Did not even know something like this

Best thing going for those of you that have cold hands. Rechargeable with usb. Holds the charge for a good time, and can adjust the heat from low, medium and high.

I use these walking around campus in NY and they are amazing. They last a long time and get almost painfully hot on the lowest setting, it's the best. I'm going to make my younger siblings get them because they are a life saver.

I recently used hand warmers at a chilly baseball game, and they were an absolute lifesaver! Right from the start, I appreciated how quickly they heated up compared to those disposable varieties. With multiple heat settings, I was able to customize the warmth to suit my comfort level throughout the game. It was so nice not having to worry about my hands freezing while cheering for my team!The warmth lasted the entire game, providing consistent comfort, which made a big difference in my overall enjoyment. The only downside was the short charging cord; it made it a bit tricky to find a comfortable spot to plug them in. Overall, these hand warmers exceeded my expectations and significantly enhanced my experience in the cold. Highly recommend them for anyone facing chilly outdoor events!
