This is a super stove. It's heat output is adjustable, and easily so. It really works as advertised, it shipped immediately, and the company even offers a guarantee.
I first did the boil-a-pint time test, and had a good boil in 5:45. Turning down the air flow, I was able to continue a simmer, just barely boiling for another 15 minutes, all on one ounce of alcohol.
This weekend, I gave it a real world test at 6500' in the Cascades, with a medium breeze. Again, it worked well, lighting immediately and cooking well. Turning down the heat really saves a lot of fuel. I really do like the ability to simmer.
It does have quite a few parts that are more fragile than a typical alcohol stove- wire pot support and feet, and a cable to regulate heat. All worked well, and I figure that if anything broke on a trip, it would still function as a basic burner.
