For 3 bucks a pop I hope a bunch of people get these to fool around with and report back. I was surprised how little water is used. I spent 10 minutes shooting the thing right into my roundhouse and will now probably do it for some cheesy effects in all my vids. 
Apparently the ceramic disc contraption is vibrated at a very high frequency which causes the water to vaporize. Makes me wonder if the stream could be controlled by varying the frequency. For those unclear, no heat is involved. As for the ‘dryfall’, not sure how much will actually be produced since the volume of water used is very low. Easy enough to investigate in the shop.
I hate oil smoke so badly now. Somewhere along the line I decided a good weathering job is preferable to the short term kick of watching smoke puffs so I run oil smoke very, very minimally now.
