I have one; I got it for my birthday. My wife ordered it online and it came in the mail.
Totally not kidding. I can shoot blue fire more than ten feet, orange out to near thirty on a still day.
A stream that provides water to the closest town runs right through my yard. I am unwilling to use toxic chemicals on the property to deal with the invasive species that come downstream so I torch 'em. It’s pretty effective on bur cucumber, porcelain berry, russian olive, oriental bittersweet, etc. etc. etc.
I let the kids play with it, too. They love it!
