Zapper comparison and feedback
Zappers are basically PEF devices, meaning that they produce pulsed electric fields. There are differences in how the signal is applied and in the magnitude of the waveform as well as in certain other parameters such as slope, positive offset, and even dwell or duty cycle.
Among the producers, there is a great degree of disagreement as to which is best for what. Often, potential customers look for testimonials but I have always said that testimonials are not a good basis for making decisions. Have you ever seen any business post a bad testimonial? They do exist. Also, just because someone has a good testimonial for one product does not mean that they would not have had better results with another product that they did not try. And then, there is the problem that in certain countries, businesses are not allowed to post any testimonials that mention treatment or cures of any disease. illness, or conditions of the human body. This is particularly true in the US.
Perhaps the best reference is third party videos and articles or blog pages that are placed by users who do not have any direct association with the product and that have tried many different products.
Following is a page of videos that were selected from nearly 100 videos posted on youtube by a highly experienced user and many different zappers and even Rife machines.

Another thing to consider: Is that product proven to kill microbes?
