Because I drausen much for hiking, climbing, camping, etc. am, I was looking for a practical kettle. For gas stoves I've just to wind always the problem that the heat is not well used and it takes a long time to water to a boil. In addition, you must always carry a supply of Gaskatuschen with and were in a fix when they are consumed. Things that I need no longer worry about with this cooker. He really swallows everything's kind of combustible and it's usually always abundant (small sticks, bark, dry grass, etc.). It is also not a lie, if it is here advertised with hot water within 5 min. - I myself was skeptical, but it actually works incredibly fast and with a minimum use of fuel! Disadvantages: The cooker is very large and who is traveling alone, perhaps ought EHR resort to a smaller version. In addition, it must be cleaned after each use. Still, he is in favor of its size easily and should therefore not pose a weight problem even during long walks. For me perfect and a strong buy recommendation!
