M-Pulse 5000 is a 5000 cycle a second AC Pulser. This means the polarity of the magnet changes 5000 times a second. I don't know if it has been tested on humans or not.
Don't know anything about the MPM2.
I own a Sota Magnetic Pulser and it definately kills or disables pathogens. If my Sota broke I would consider buying one of these
Super Magnetic Pulsers in the link below. I is the same as a Sota but pulses up to 15 times a second. This could save a lot of time as you need at least 20 pulses on each area to be effective. It is also suppose to be heavy duty. It shouldn't be to hard to repair your Sota. Probably bad capacitors.
