I use the volcano2 all the time. I actually use it for my Scouts regularly and for my business. For my scouts, we regularly bring it to meetings and do dutch oven whatever. As a matter of fact, next month, the scouts will be doing a dutch oven cookoff. The leaders get to judge.
When we are done, I can quickly dump the ashes out in a safe location, collapse the stove down, and within just a few minutes, put the gear in my Durango and head out. We can do wood, charcoal, or propane just about anywhere without a trace. It certainly isn't for backpacking, but it is a remarkable piece of technology.
In my business, we teach preparedness at www.simplylivingsmart.com. My business partner actually shows dutch oven cooking in the volcano ii. It's a great tool to have at home or with scouts.
