I bought three different flame effect PTC style "miracle heaters". Two turned out to be the same style despite having different listing pictures, and this one (which cost the same!) turned out to be somewhat less complex (huge understatement).
I think the best way to avoid this heater is to make sure you buy one with a remote control. This one does work, but is perhaps a bit simplistic compared to the others.
It is totally scavengable though, with a pretty good flame effect and useful heater section that could also be a source of resistance wire for custom heating elements.
It's notable that the rotating mirrored mylar blades give a great scaled down Star Trek warp-core effect if used with blue LEDs.
This unit is freestanding with a thin flex of unknown electrical integrity, but I think we can safely assume that it will be the crappiest copper coated aluminium type stuff. It's also easy to knock over, so that thermal fuse and plastic front grill may be tested at some point.
The schematic does bear a strong resemblance to a hair dryer with extra effects, and that is kinda because it is...
I specifically avoid using intrusive mid-run video adverts for a more relaxing viewing experience.
