Actually, any zapper can have some good results and testimonials. In fact, there are 2 different versions of $10 zappers and both have had positive testimonials. So, if all that you need is testimonials, then you could buy 30 of either of those for the price of the ultimate. and actually, I would consider one of them to be better made than the ultimate.
The most important thing is statistics. What actual percentage of users with a specific issue will get good results. All of the testimonials that is posted on the ultimate site is only 1 percent of the customers. What about the other 99 percent?
