Does anyone have any experiences with Bob Beck's silver pulser (or blood purifyer?). I have used it for a week, following Beck's recommendations of using cotton to protect the wrist from getting blistered or burned. I wrap a small piece of cotton once around my wrist, place the metal parts on top, under the plastic wrist band. This morning I burned one wrist pretty good, have one to go. If the other wrist gets burned ,too, I'll have to stop the process, altjhough I don't want to . Please help!!! Should I use more layers of cotton??? Lower the pulses???
