To share a different experience, I've used a Pocket Rocket ever since they came out, and have no complaints or bad experience. (It did fail to boil once, but in all fairness, it was on a push-the-gear-limits January trip, and zero degrees. smile ) A friend of mine has had equal success. In case locale and type of user might affect the results, I would point out that we are both strictly recreational, weekend hikers, who hike in the Eastern US forests, and use it to boil about 12 ounces of water for freezer bag meals, and maybe make a pot of coffee or tea.

I've also tried the Snow Peak Giga, but found I liked the Pocket Rocket better - as with many of my other gear decisions, it was more subjective than objective, as I never had any problems with the Giga, either.
