I've got the west German set and can't rate it enough! You can make stew in the main pot and have bannock cooking in the inner top pot at the same time. Breakfast is easy as well, bannock in the top while you brew tea and cook with the lid, or beans in the inner top pot while you boil eggs, etc.
It keeps ash,bugs and sand out of your food while you cook, can be hung over a fire with the bail arm, sat on a fire or sat on a hobo cooker. You can also keep stuff dry inside it strapped to your pack or bergan with your hammock biners. Well worth the £4.50 endicotts do them for! I wouldn't go out without mine! I've tried lots of other things but this is the one for me.
