Strange . Have you researched rife machines at all.. its quite same as zapper as i know but better and more expensive. I have a couple though and would be willing to give u for half price or less. + i have international shipping discount of 75%
great for parasites, and theres really 100's of uses . But finding the source of problem may also be key first. but doing sweeps on the rife machine for parasites or something else it may be could be very helpful and doing the different sequences for all different parasites could only help if it were that...
Well if u have money to spend its a wise investment, and would hold its value, its complimentary to everything and also has 100's of other uses. I would recommend. let me know if interested in more info
