Zippo
Big problem

This hand warmer has no reasonable way to turn it off: once you start it, it runs until the fuel is gone, 6-12 hours. So you have to hold it the whole item, or put it down somewhere — you can't put it in your pocket, purse, or anywhere enclosed for fire reasons. Fine (maybe) if you are in the Alps, but for every day use this is ridiculous. And their web site does not tell you this, only the instructions.
