I had a friend get one with the same results. To test them you can submerge a straight sheet of aluminum foil and it should start eating holes in the foil. His changed the appearance of the foil but no holes.
That's very cool, thanks. I can already tell you with great certainty mine will not do that. I wonder if there is a fix for it? I've often thought about if maybe it had an electrical adjustment inside it somewhere.
