Re: UZ and spasms - question.
>- Ultimate Zapper is the most powerful
Actually not, The "Medical Electric Battery", invented ca 1890 was more powerful. Tens of thousands of these were sold up to approx. 1936 when the company closed. This DC voltage zapper was sold by reputable establishments such as Montgomery Ward, Sears & Roebuck, and many pharmacies. It was patented but the patent expired and there were clones.
I own several of these machines and while they do not entirely meet Dr. Clark's specification, they were effective and well reputed, even coming with a thorough instruction manual and had many accessories.
Also, while the UZ may have a stronger voltage output when using a wall power source, ParaZapper likely has a stronger total power output. Also, ParaZapper MX-2 and ParaZapper AV-2 have essentially a 18 volt p-p output with 100 percent effective duty cycle and 100 percent positive output at an effective 9 volts (9.6 - 10.0 volys on a fresh battery).
Of course, ParaZapper does not sell zappers for use on humans or animals due to oppressive US government (FDA) regulations.
