    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?

      From the video a good tell is having a metal basin, also the waves in the liquid when turned on should be grid like rather than wavey waves, finally put some tin foil in and it should come out with wee little holes in… YMMV I guess
