I got scammed on eBay (what a surprise)

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't hear the ultrasonic sound because it's ultrasonic, you can still often hear clicks from the piezo disk as it changes 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. Seller - "It is what it says it is, i have sold many without issues...i do not accept returns and this is stated on ebay. I can give you a partial refund as a good will jester. Alternatively take it up with ebay..Good day" Me - "If you look at your stock then the label clearly states Ultrasonic pest repell , and that is exactly what it is. I've tested it, and it generates no ozone whatsoever. I would like a full refund, and would suggest you change the listing to indicate what the unit actually is." No reply from seller after 5 days, so escalated to a case. Minutes later eBay provided a full refund.
