I got an AC powered unit off Amazon a couple of years ago. How can I tell if it’s fake? Jewelry comes out bangin’, but I’ve wondered it if should work even better.

Wife got this stuff last week and it seemed to make a dramatic difference.

OTOH, I can’t see this thing having a legit transducer. Anyway to tell without tearing it down? Guess that’s easy enough if I really care.

Should I try something rusty? Should a “real” one work for that? Also, it gets the water pretty hot. Is that an indicator?

If you need an ultrasonic cleaner, just go to harbor freight, they have decent ones for cheap. I bought one a few years back for carburetor parts a few years ago, and it does a great job

I bought a fake one off of Temu. It was so cheap why not.

Instantly knew it was fake once it was in my hands. Tried it anyway. Clearly just vibrating.

Returned it. They told me to keep it…

Everyone knows that ultrasonic cleaners are great

Mate, wtf is an ultrasonic cleaner?

Edit: this is a rhetorical question, I’ll read the article.
