In my experience they make a lot of smoke and not very much heat. None of them big enough to make a proper blazing campfire which is what you'd really need if you are just in the open.
Suspect digging a big sunken pit would make quite a difference as per pic
On my wish list if I win the lottery is something like this for smokelessness
Cool, thanks for the response, prob won’t bother then. I’d only be buying a tiny one anyway so if it’s not gonna chuck out any heat it’s not worth the cost.
