I go this year the Alpe Adria Trail and want myself self-sufficient again. To cook for five people I would not use the course, but only to heat water a great thing. Ultralight and trotzkdem perfect! 600ml water are boiled in 7 minutes (this does not use a windshield - with the cooking time would be shortened by approximately one minute). It is, as the name just says an Emergency Cooker and no mobile kitchen. With a bottle (or tube, or small bowls) Brennpaste with the luggage that you simply refills the tank, you have no problem. For longer distances, however, I would take two or three of these Emergency Cooker, since the sealing ring in the ceiling at some point could be leaking and the Brennpaste then ausraucht. For my purposes absolutely perfect
