You might want to note that just because it works under the microscope, does not mean that it will work in vivo.
Consider this.
ParaZapper offers a 30 day money back guarantee that is definitely honored. Check with the Better Business Bureau. In 13 years of business, we have never had one single complaint from a customer. You do not see reports from any of our customers complaining how unfair we were to them.
We receive between 4 and 8 returns a year and almost all are because the person who bought the zapper has a stainless steel implant or other issue that can cause problems. We get 1 or 2 complaints that it did not help someone.
The funny thing that I do note is that sometimes the units do not always resolve the original problem but they do resolve something else so the customer keeps them anyhow.
