Boiled water in about four minutes at 9,000 feet, which honestly surprised me. The whole thing nests down compact enough to disappear into my pack's side pocket, and the burner simmers low without scorching my oatmeal.

Took this on a three-day hike and the compact design fit perfectly inside my cook pot with room to spare. The heat output is genuinely impressive for how small the burner is, and I never had to babysit the flame.

The system boils water fast and packs down small, which is what I wanted for solo trips. That said, the pot wobbles a bit on the burner unless the ground is perfectly level, and it's heavier than my old setup.
