Seems a tad heavy: 8 ounces for a stove and pot that will heat about a cup and a half, or two cups, of water on one tablet. For the same stove/pot weight, a Pocket Rocket or Snow Peak with a titanium pot will heat twice as much water substantially quicker. Of course, I don't know how many Esbit tablets have the same heating capacity as a 110g fuel cylinder.

I played with Esbit, and could get it to work. Of course, I never repeated the experience.
