This is dirt cheap, light-ish, and excellent.

To get mostly-smokeless performance, leave out the bottom metal plate when you assemble it so it gets continuous air flow right through the device. I used to use https://www.solostove.com/en-us (car camping only) and it just burns too* clean - no smoke, hot fire, goes through fuel very fast, and all the heat goes straight up. Still love that thing, but actually for an "improved campfire experience" that collapsible grill thing is excellent. Particularly useful: the heat reflects off the inclined metal plates right on to the people sitting around the fire, in exactly the way it does not on a solo stove.

It's really good. Makes me happy.
