I'm sorry, but that stove is incredibly cool! I question the heck out of it and its durability for its advertised purpose, but still..... Worst comes to worse it breaks and your still cooking using wood.
Stove wise, I use one of the gasoline burning stoves MSR. It works just fine, extremely reliable (4 months of daily use with no issues whatsoever) and never had any flaring issues. I've also used a canister stove a lot and like using them as well, but not finding the canisters....
