Is the PEMF device similar in mechanism to the device Royal Rife had promising healing results with? What can Creator tell us?

This is within the same family mechanistically. As you know, he was working in an earlier era, and so the technology of today approaches the desired goals in a somewhat different fashion electronically. But that is not what matters. What matters is getting a beneficial result that suits a given client and their dilemma, and you have our blessing here for this client being a match to what this device can offer.
