Either Beck was just wrong or misrepresented the case. I like to believe that he was just wrong. It might have been that the one or two that he tried might not have worked.
The fact is that There has been far more Clark zappers sold than Beck and even those who have bought cheaper less effective zappers have had positive results.
As of yet, I have not seen you post a demonstration showing that a Beck zapper or a Pulser can clear a jar of microbes in 1 hour as I have demonstrated using ParaZapper CC2, UZI-3, and MY models.
There are also several videos on the internet that fully demonstrate that Clark zappers can effectively kill microbes.
I understand that you are wanting to keep competition out, but really, complaining about a free e-book?
