Negative Positive
Title: Unremarkable results, maybe unreasonable expectations?
Review: I purchased this not really for it's intended purpose of cleaning jewelry, but because I remembered a childhood friend using one to clean off carbon deposits on spark plugs. I figured that cleaning hearing-aid tubes would be a cinch.Well, it seemed to have no effect on hearing aid tubes. So I tried a few more things and the results were not remarkable. It may be great for jewelry, but I just don't know.
Is the review positive or negative?
