    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?
