I may not have 40 years of research behind me, but I got rid of all my parasites with a $10 Zapper and I'm just happy for any one to have any Zapper at all! Maybe yours does work better, but I sure don't know it from experience because it's not in my price range and I really don't mind using Dr. Clark's research for reference if she's the only one who will publish it.
Using less money to get the same results is called inititive, and I pride myself for any amount of it I may have. "Who can find a virtuous woman? Her price is far above rubies."
Sorry if I pushed any of your buttons, and maybe I shouldn't have a personal opinion like that, but you are entitled to yours too.
