My brother has one. I have used it with him a few times and it is lower smoke but not no smoke. I was able to stand around it for quite a while and no strong smoke smell but my clothes had a faint chemically smell afterwards possibly from some unburned gases I don’t know if that is normal. Maybe my brain just imagined it because I expected to smell something but my wife who was not with us could smell it on me as well. I was surprised how completely the wood burned. I am still debating if it was worth the price.
