$15?!! Did you use a gun and wear a mask?
These cones are really nice. Would I take them out at -10F for snow melting? Not only no, but HECK no, but for fair weather (the majority of my hiking), they're great. These are what I call "fire and forget stoves." You fire 'em up, and then you forget about them. Come back in 10 minutes, and job done. I usually go set up/break camp or whatever.
And the silence. Ahhhhhh. It's really nice to have almost total silence. Yes, the roar of a stove in the evening can be the sound of supper, but sometimes silence is really nice too.
