High quality portable urban and camping stove or fire pit.  Our primary use is to do smores at home and we live in a townhome with a large deck area.  Since the stove, is lifted off the deck surface the heat doesn't affect or damage the surface.  The stove is nearly smokeless and we haven't had any complaints from our neighbors.  The key is to have your wood short enough in length to completely stay inside the diameter of the stove.  If the wood is burning outside of the stove, above the top ring, obviously you will get much more smoke.  I've been using 2X4's cut to around 10" in length and then also split them with a hatchet to make kindling.  Works great!
