Bought these for my roommate the time; she always found herself in "the wrong company".... if you know what I mean. Nothing bad, just shady people. Anyway, I attached one of these to her keyring// for personal defense.
I used the fuel cubes in my pocket stove to heat some water for coffee in my canteen cup. One cube was enough to get the water hot enough for my liking. The Esbit Solid Fuel Cubes are a great heating source for any camping trip as they will take up very little space in your pack. Its a lot of heat in a little cube.
