These $2 stoves are a great deal. Buy them to hand out to friends at Xmas or gift them at other times like stocking stuffers or Bdays. You should make some yourself out of cans to understand the build process. Knowing how to build a field expedient stove out of 2 cans is necessary field knowlege in my opinion. These are great buys at $2 primarily due to them including the fuel bottles as well as the screen. Usually, that 3 piece set will run about $10 on sleazebay.
