Hand warmer is great. Like a portable heating pad. Best hand warmer i have ever invested in.

These are very reasonably priced. I am tall and skinny and my fingers freeze easy, but no more. It means if i get a little cold the blood vessels in my hands and feet constrict and get cold.

You turn it up to three to be greeted by something that might save your life. Charged them completely w/in 2 hrs. Other than the suspect battery life, this thing is great.

Avoid this product and seller. Amazon take this back and refund my money. This is actually * in several non us countries, but they're allowed to blatantly scam people here.

There is no electrical cord included, not the type that can plug right into a wall outlet. They only have charger cords that have to be attached to some other electrical device. The battery life is extremely short, much shorter than advertised.

On low unit almost too hot for bare hands. Temperature is incredibly inconsistent. It is unbearable so i resorted to wrapping them when i used them.
