Love this hand warmer. You can either charge it from a USB or it comes with another attachment so you can charge it on your phone if you can't find a plug in. And if you have it on the highest temp, you better have gloves on. It's hot and works great~!

Warmth WAS totally awesome and battery life was great. Bought in April then on and off button got stuck in August. Paid more for this as thought it would be better and it was for 4 months. Worthless now.

This product is amazing! It helped me to keep not only my hands warm but my entire body in a camping experience. You can put it in your pocket and you will feel warm immediately. You can put it next to your bed and the coldness will fade right away. It’s also, stylish and very soft. I love it!

My wife's office gets cold so I got this for her hands. She says it warms very quickly and stays warm for a long time and she only uses the first setting (she says that's plenty for her). Happy wife, happy life :)

This is the most easy to hold hand warmer I have bought yet. It heats up much more quickly than other hand warmers and gets very hot if you choose Level 3. I have only had the warmer for two weeks and highly recommend it. I have not yet used it for more than an hour at a time so do not know how long it will last between charges.
