for those that dont know, this is a copy of the british army hexamine stove / tommy cooker / ration cooker that is issued to troops. you'll not boil spuds etc unless you have lots of spare fuel, but that aside, you can heat tinned foods / soups etc / make tea and hot drinks etc. they are really a throwaway item, or you could bag it and reuse a few times. get a few, and loads of spare fuel. these tablets are tiny compared to hexamine. you can get those or american gels online. i use this cooker and the others and mess tins to fry sausages, potato bread beans and soda bread. you are best having 3 lots of fuel a day for breakfast and lunch ( rations that just need reheated)i'd suggest and a lot of matches. use it out of the wind, ie dig in in a hole etc. i use them for the novelty, but they do eat fuel!! some have a shaped lid that holds the pattern 58 army mug safely in place. i have 6 of these and spare fuel for a few trips. suitable for hikers who need a ration heated and a hot mug, or get more fuel for camping for a few days. it does work well though when shielded from the wind.
