I like the Storm ... the only real complaint I have is that the flipped lid only flips 90 degrees or so, which puts the lid a bit in the way in use. It would nice if it flipped all the way over - like the Zippos do. As I recall, the Windmill does about the same thing (not flipping all the way over) though a bit better. Silly problem.
Boy, I haven't a clue as to how long a butane load lasts. It would seem prett easy to time it, though I'd worry about leaving it on too long and maybe melting some parts.
