I picked up a Solostove Bonfire just before New Years. www.solostove.com/solo-stove-bonfire
We've taken it put on two trips, and it fits on the floor or our Hawk (rollover couch). We fill it up with newspaper and wood cut down to ~12-16 inches before we pack it in the camper.
Before purchasing it, I was intrigued by the claim of low smoke production. While it does produce smoke, especially as the fire is starting up, the level of smoke production is lower than you'd expect once the chamber heats up and the secondary combustion kicks in. When that happens, the fire is visually unique, as it whirls fire from each of the upper vents. It's mesmerizing!
Overall wood consumption might be a bit lower than you'd guess, but it's not remarkable. The small quantity of ash produced is very noteworthy, as is the overall amount of heat produced.
It was $299 when I picked it up, which is about $299 more than I'd ever guessed I'd spend on a fire pit, but I really, really like it. It's made in Texas, and the materials and dual-walled construction seem top notch.
Look on YouTube for some more reviews, and you'll be sure to see the spirals of flame that everyone comments on the first time they sit by it.
