I LOVE my penguin lighter, I've been over this I think.... no clue what kind but I've had it for almost a year, and no problems. Its a tad tarnished, and it's using more butane now than it did when I got it... dunno why, but I seem to be refilling it more and more often. maybe my friend is dying Lately I've been carrying him and a nice blue BIC everywhere I go. You never know eh? and I'd hate to pack a bowl and go to toke and click my penguin (electric light) and a little pussy ass "low fuel" flame pops out of his neck
