some machine details

I was using the classic beck magpulser as a daily lymph area treatment.
I assume that the sota is pretty close to the original beck magpulser.
The mpulse says says something about using AC power as being more effective, and also that they use 1700 DC to produce their pulse which is more than some others. This one looks like a step up from the orginal beck and pretty similar in usage.
The MPM looks very adjustible with multiple frequencies and one or two battery options. However, I am worried that it would be too strong for me. Also, I do not tolerate my rife treatments well and can only do them once every 2-3 weeks. This machine is frequency adjustible, almost like a hybrid rife-magpulser, which seems a stronger mix and I'm not sure if its suitable for a daily use like the one I intend.
Anybody used more than one of these machines who could comment?
