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.

it's everything 😀 slices dices and cleans your dishes, irons your coat and slims your wallet!
A scam error… It's probably just a labelling error and a clueless picker. I had similar occur on Amazon where the picker would be even less likely to know the discrepancy.
I feel like I am doing something wrong, but….I was more interested in the fancy screwdriver than the scam product!

Well done Clive I hate those cocky eBay sellers you can’t touch me lol, I hate the power sellers that have a score of like 150,000 and when you look at the feedback they have like 300 negative feedback in a month, and still trading ! They state in the uk, but from china and still take weeks to come..I got removed from eBay selling because I received too many 3&4 stars for P+P, rant over thanks again Clive 😊
I was just thinking its past time for an ozone generator video.
Clive. After reading the description I have to agree that we can hear things produced by ultrasonic devices. Also there's a funny thing when we listen through microphones, we can hear frequencies half that of the main frequency, then a quarter etc. It's why if someone were to blow a dog whistle we can't hear it but we can on video.
Glad you got a full refund, thanks eBay. 😃👍
Maybe ran out of parts
and add sold incomplete
Only Clive would know
The housing looks nice 😊
I'd put this down to confusion before I suspect them of malice.
I have that same one. I think it only repels saber tooth tigers because I've never seen one when this has been plugged in.
I see it does have a CE logo on the box, like some version of it was sent for certification. If it’s just got random electronics in it, then the seller is misrepresenting it and it’s safety.
I bought a similar type, different form factor and USB. Upon asking for a refund, they offered me a 15% refund and I could keep the “product” which they explained does ALL sorts of things.
In short, I got my 100% refund once eBay stepped in.
