My turn to be scammed on eBay (Patreon)

Normally when I buy scam products I know what I'm buying and get them to explore and reverse engineer, but this time I bought what I thought was a non-scam product and it was a completely different product in the case. For those who will inevitable say that I can hear the ultrasonic sound because it's ultrasonic. You can still often hear clicks from the piezo disk as it changed frequency or resets the sweep. The piezo disk is just a token gesture here, since it would need a resonant cavity to put out any significant ultrasound, but in this case it's just glued in on one edge. It's very clear that the case was originally intended for use as an actual trace ozone generator, but ended up being repurposed badly. Possibly due to a flaw with the original product design. The most interesting bit of the design is the odd half-wave capacitive dropper. I wonder if it was intentional or a fix for a design error. eBay case is open as "not as described" and awaiting seller response. Two pictures were sent. One of the box and label, and a close up of the label.
