Best Zappers? Ultimate vs. Harmonic Quad vs. M7 Bio-Energizing Zapper?

Well after exhaustive searching and reading, it appears that the three best Zapper choices are The Ultimate Zapper $150, The Harmonic Quad Zapper $350 or the M7 Bio-Energizing Zapper $300 (they also seem to have a $150 model called the Genetic M4).

Given a condition of intestinal parasites, the only one that is capable to work deep enough in the intestine is the M7 from the Philippines - according to Dr James Overman - though he recommends against it because he claims it kills good parasites as well (but then he sells his own brand - the Harmonic Quad Zapper) while the people that tout the M7 and the Ultimate Zapper say baloney and that theirs only kills the bad parasites or that you can't kill too many (and of course they sell theirs).

Anyone have any less subjective recommendations or experience with the M7 and M4 or the other two? Tweet
