I said that no organic materials which would indicate that the device worked were found; clearly finding skin samples alone would not be proof that the device worked so they would not bother to test for that.
They found nothing in the water which could not be explained by electrolysis, is that unambiguous enough?
Let me know how your test turns out, the one that you ignored in my previous post, the one similar to the post that started this thread! You know, the test where you add the salts for conductivity, turn on the foot bath with no one in it, and see what happens. Please post your results here, as truthfully as you can.
