I really liked this idea and the video made it pretty cool. However, upon applying, I found that there are some serious design flaws and it is absolutely dangerous to use! My first observation was that it doesn't glow well unless in flashlight mode, even indoors with no wind. If you want a simple flame you have to light it in torch mode and then turn it back into a flame, which isn't a big deal but definitely doesn't work as advertised. I also noticed that the bass and treble controls don't work very well. Turning it up or down sometimes didn't affect the output, which is pretty odd and generally feels cheap, lazy, and unreliable. The icing on the cake is that after about 15-20 test lights the pen caught fire and of course I dropped it on the floor. Because it's round, it rolled under the chair next to my rug and nearly set my room on fire! Thank god I got to him quick enough before he could do any real damage! I would definitely say this is NOT SAFE and is now legal for outside use only and kept in my garage away from combustibles. Highly recommend buying something better if you are looking for a large handle torch as it does not live up to expectations.
