This is basically like a double version of the exponent xtreme. It collapses so that it doesn't take up much room in a pack, but expands to easily cook two pots at once. very lightweight but easy to use.
This stove is incredibly useful and functional since it's a double burner. However, it is still very light and doesn't take up too much space in your pack. Finally it's very fuel efficient even if your running both burners on full. A great stove for when you have many people or need many sources of fuel.
Whereas I do agree that this stove is certainly light enough for a group of three or more and very fuel efficient, it is darned awkward to pack. The odd folded shape and length of it inevitibly have me searching for something to roll around it.
Now, that said, I have yet to find another stove that allows me to simultaneously boil water for a meal for four while melting snow for the water to get through the rest of the day. And the PowerMax fuel has yet to let me down while at 7000'+ during winter. All in all, I really do love mine.
