Cute and hot.
Tiny little Japanese stove that heats really well! 1 cup of water takes about a minute to boil. If you're doing a long trip, bring matches and sandpaper as all piezo igniters have the same problem - they build up carbon on the tip and don't spark as well. So sand off that carbon and it should spark just fine. Un-documented second function: if you ever want to wake yourself up in the morning without coffee, just touch your thumb with the spark igniter and hit the button. YEOW!
