Puff. What are you refering to? Actual results? I don't think so, - remember you aren't sick. I don't know what you are using to test your stuff, but it's really honestly annoying to read your (obviously) biased opinions. You have every reason to promote your Zappers, don't get me wrong, but it doesn't mean you are the authority on every other Zapper. Other Zapper sellers do testing and such. My ZP is at about 23 kHz, so I don't know what you are testing with, but since you are so sure that frequency is the big difference then of course you would believe the ZP is inferior. Get over it. You still don't have any documentation on results vs. results. As for the size and look of the ZP, sure it's not fancy, but it's conveniantly small and saves a lot of battery. The price is a huge difference in my honest opinion, so I really don't think you've got any thing on it.
