This thing is awesome! For the price I want to buy several of these and put them everywhere! Used it on a backpacking trip and it out performed my friends stove and was so simple! Also lost power while cooking one night and I used it to finish cooking some philly cheese steaks. Are there more efficient lightweight and sturdy ones, probably, I have used a jet boil and they are amazing, but not $100 amazing. Now this thing for less than $10 is amazing for what you get.
