I have a theory that on people that the Sota Silver Pulser or (Beck Blood Purifer) does not seem to work on may be caused by a high skin resistance, thus not allowing enough current to get in to the blood. Do you feel a slight sensation in your hand that you have the probes on while using the sota silver pulser? I am betting that you do not and you can most likely stand the unit being on full blast with no discomfort. Let me know if I am right, it will help me in my research.
