Title: Don't buy it!
Review: Despite their claims, this handwarmer is mediocre at best. I bought two of them. One works for about an hour, the other quits after 2 to 3 hours. They never get very hot, despite using the best quality fuel. I went back to my good old Jon-e warmer, which gets so hot that you have to keep it in an outer pocket. Stick with the tried and true and don't be mislead by outrageous claims! I wish that I could get my money back.
