little of what can be called hype
>- using several specific frequencies (chosen how ?) instead of one is arbitrary
No, just because it is not published does not mean that it is arbitrary or that it is ineffective.
>- there is no proof that it is more effective to kill some harmful organisms.
There is reasonable proof that it is far more effective in killing microbes in water. That is the ONLY claim that we make, because that we can prove without legal issues.
We can not afford to and do not have the time to test it on everything. That is the very reason why we offer a 30 day money back guarantee. We do not want you stuck holding a product that does not live up to your needs and expectations.
>- that's why some people will keep buying your devices
Actually very few buy because of hype. The great majority of our customers know someone who has used and had significant visible results.
>- (i was one of them in the past)
You have never purchased or used ParaZapper. You have stated so yourself. So, you do not know anything about it.
>- There is a never ending stream of ignorant stupid gullible people with money to throw away
Actually, many of our customers had previously been through the same thing as you. They bought junk from hype.
If you even bothered to go to the site where we sell zappers, there is little of what can be called hype. There are no medical claims, no claims of cures or treatment.
Nothing but disclaimers and a 30 day money back guarantee. Even our testimonials have been stripped of all of that.
How many of those that you bought from offered a money back guarantee? When they did not help, why did you not ask to return for a refund?
Especially, you stated that at least one expensive unit was DOA! Why did you not at least get a refund for that?
A lot of what you said does not make a lot of sense to me. You know, PayPal offers great buyer protection. Even Most credit cards offer buyer protection. If you get something that does not work, they will go to bat for you.
This is why you appear on many occasions to be a troll. You have not done what most normal users would do. They may just write off a $30 or $50 product but most people are not willing to toss $100 and not raise the roof if it does not work. Especially if they spend $200 or more on it.
