I examine the SmokeNinja fog machine from the company of PMI (which stands for Practical Magic & Innovation, though the logo is largely illegible and they only mention what it means in a tiny font in one place for some baffling reason). Despite them being embarrassed by their own company name, it seems to be a very well-constructed, well-designed and well-implemented device. (That’s 3 out of 3 “wells”, my highest score yet on this new scoring system I’ll never use again.)
It puts out a decent amount of smoke/fog, is easy to use, remote controllable, and has a user-swappable common type of lithium ion battery so you could use it extensively.
They pitch it for photography/videography effects or theatrics, and I guess it’d almost certainly be good for that. Now that I think about it, it would also be good for Halloween effects on the front porch or something. Though, I purchased it for the purposes of showing the airflow in computer cases, as well as the beam dispersion patterns of lighting fixtures.
