I bought one of
these because it looked kinda cool. No surprises, it doesn't work very well. It's awkward, difficult to use, and kind of bulky.
I also have a few of the Vietnamese coffee pots, but I don't know if I can handle the coffee without the ice and condensed milk, it just seems wrong.
I'm about as coffee snob as they get, but I just rough it when touring. I figure even mediocre coffee is better than no coffee.
And don't get me started on tea, I won't touch tea touring because I know I can't do a decent job of brewing it (If anyone mentions a bag, I'm leaving).
