Convenient and quick, but bulky
Pros: Lightning quick set-up and intuitive design. The fire starter switch is very convenient, and everything nests together pretty well. As for cook times, this thing boiled water faster than any home kitchen I've ever used. If you ever need to level some underbrush, or just boil some water fast, the Helios gets the job done without using as much fuel as comparable designs.
Cons: The price hurts us dirtbags a bit more than most, and you only get one pot. If you're cooking for a group, obviously you'll have to augment your backcountry kitchen set with more cookware, but if you're flying solo and don't mind lugging a slightly larger stove around, you can eat like a king.
