Great little cup
I've had this cup for several months and have used it for three weeks on a mountain trek in Greece as well as on daytrips.
The quality is great (just as good as higher priced titanium cups and pots) and the cup is very light.
It's best used for boiling some water for tea or coffie, since it's too small to make a meal in. Works well with both a gas burner and an alcohol burner. Haven't tried cooking with it on wood fire, but I think the cup would be too small for that.
