My son-in-law bought the big Solo for his patio - it really puts out the heat and flames and no smoke. The only fault I can find is that staring into a fire is mesmerizing/relaxing; and the tall sides of the big solo means you don't see much fire once it burns down a bit.
I just bought a couple of "campfire in a cans" - basically more of a candle for staring and infinitely more portable than a stove. Probably still would be banned in areas where forest fires are a threat.
