I bought a small (backpacker) version of this stove to play with, and it worked so well that I bought the large version to use as my outdoor cooker. What I like about this stove is that fuel is laying around everywhere. Sticks, pinecones, scrap bits of lumber from construction, and junk mail, all burn in this stove really well. So I get to clean up my area, every time I use it.
If you let the flame die down to glowing coals, there won't be as much carbon on your cooking pot. I've been told to coat the outside of the pot with liquid soap to make cleaning easier, and it works very well. You can also cover the bottom of the pot with tinfoil to keep the black off.
The Solo stoves are a great tool to keep around your homestead for power outages, going camping, picnicking (What's cool here is they can be used where open camp fires are illegal), and survival situations, where you need to cook some food, and boil some water to purify it. If you have a fireplace, you can sit this 'little jewel' inside it, and cook a meal right there, inside your home.
[Take care, and keep the fires a burnin'!]
