This product is awesome!!! My husband is a police officer, who works nights. This hand warmer seriously works well. It gets super hot/warm extremely quickly and lasts all night.

This little gadget has been invaluable while skiing, snowshoeing, and camping. I have poor circulation and my hands get completely numb. This has been a great quick fix. Also makes crawling into my now warm sleeping bag comfier.

Perfectly sized for even small pockets and surprisingly powerful. Exceeded my expectations for size and heat output. What remains to be tested is longevity and reliability

I really like this little hand warmer. It works great. I have been using it on low and that is perfect. Easy to use. Fun to hold and keep your hand nice and warm.

I bought this for the hunting season and I am so happy with it. This little thing pumps out some serious heat. It has three heat settings. It is easy to use and the battery life is much longer than expected.

I bought this for my wife, who is constantly cold, on a lightning deal. She uses it off and on all day, from her walk into work, to inside her inefficiently heated office, and back out to her car. She absolutely loves it, so I do too! Considering buying a couple more for my hunting season

I work in an office that's rarely warm enough in the cold winter. Since we're not allowed space heaters, this handy little device works perfectly to keep my hands warm. Have given these as gifts as well!

I bought this as a stocking stuffer for my daughter. She is a pizza delivery driver and during the winter it can get brutal running in and out all day and evening. She told me it's one of the best presents ever, and lots of the drivers in her store have asked where it came from.

This is the most amazing gadget. I have 3! There's usually one in the car, my purse, and one ready next to the dog leash. It heats up within seconds. I've purchased 2 additional ones as gifts. I recommend it to anyone who is frequently cold.

This hand warmer is great. It heats up so fast! I just received it, haven't had to charge it at all yet and it is working great. I have Raynauds Syndrome, which is poor circulation in my fingers and toes. The only way to get them to get blood back into them is to warm them up. Raynauds is an awful feeling, and this helps relieve my symptoms before they get out of control or my fingers and toes start turning blue. Highly recommend.
