Two hand warmers which clip together for easy storage or when not in use. Reasonable instructions for use in the pack and everything needed to set up quickly. Once charged the battery lasts a long time. Can be used held in the hand, in the pocket, or inside the glove or even better mitten. Inside a glove finger ends can get cold. They warm up quickly and the heat output can be adjusted easily. Better performance than any chemical heat pads tried and are multi use. They are unobtrusive, interestingly shaped, and easy to use, the long-term answer to cold hands.

Work well at keeping hands arm

I bought these as a gift for my dad. They arrived in a nice little box.They work well and are usb chargeable. My dad was buying the disposable hand warmers before this. These are much better!

These hand warmers are great, I have only used them on the lowest setting to be honest and that's warm enough for me. The battery life is also fantastic, over all I'm really happy with my purchase.

First time clipping together proved exceptionally difficult, a child or person with arthritis would never be able to do it. After the first few times they clip together easy. Magnet would be more suited. Not the best heat and nowhere near the temps can be reached in very cold weather like all warmers claim but they do the job. Not quite sure on how long they will last only time will tell. Got the price could have been much better but for small hands they are great

They do not work!!! Do not buy!!

Brilliant hand warmers perfect for this time of year great price last for quite a while before they need charging

Bought this hand warmer in the later part of November. Started using them at the beginning of December because the weather has dropped significantly in the evenings now.Product is made of Black plastic. Lights to signify its on. Can be attached together (not magnetic) to form 1 hand warmer. When used individually, the heat is on one side of each warmer.3 heat settings in total. Found that even on the 3rd setting it wasn't sufficient enough to make a difference to cold hands.Thought I had a bargain at just over a tenner. Wish I could get my money back, though. Not something I'd purchase again. Maybe someone else will have a better experience. I've had to buy another one.
