Zippo Hand Warmer with 4 Ounces of Lighter Fluid

It works well and keeps your hands warm.

It does just what it said it would and gets warm and keeps my hands warm. I would suggest one for each pocket in extreme cold. My fingers are ever happier!

This hand warmer does a very good job. It is solidly built and lasts a very long time. I give it 3 stars due to what I consider three design flaws. First, it must be kept in a provided pouch or it WILL burn you. Second, You need an additional lighter to activate the warmer. I would prefer an integrated system. Finally, you cannot deactivate the warmer without somehow prying off the top. This is awkward at best. I have no experience with the competition for this device, but to me these are issues that keep me from using it more frequently.
