Bests & Worsts Reviews from Amazon

In my lifetime of building, designing and managing technology and communications engineering systems I could not identify any theoretical physical principle that would allow anything stuffed into a cheap outlet plug from China to "eliminate EMF throughout the whole house". I asked several of my employees - Electrical Engineers who have managed warship nuclear reactors - and they asked if I was feeling OK. So with this thing in hand, I wanted to see the amazing technology that negates physics; to discern what the learned scholars (who no doubt would earn a Nobel Prize for their efforts) discovered! The answer: goop. Yup. The physics-defying technology involved appears to be little more than a dollop of cheap ceramic epoxy crammed over the ends of a $0.58 outlet plug found in bulk on a parts supply website. Ceramic insulating goop is also pretty cheaply had in bulk. I could explain the concepts behind EMF radiation, how it forms and how it propagates. I could even regale you with lesson learned as I have applied wave propagation theory to emitters throughout my career. At the end of that I would tell you (as I did the buyer of this device) that there is no scientific principle recognized by any respected physicist anywhere in this world to explain how a dollop of cheap putty placed in a bulk outlet plug can do anything to "stop" EMF emissions throughout a house. Just. Not. Possible. I could explain all that, but a certain percentage won't care. They are the true believers. They will assign to me labels: "corporate fascist", "foolish sheep" or something of the like. I am not writing this review for them. I am writing this review for anyone who is on the fence - the person who worries about the effects technology might have on their person, but does not actually understand enough physics to discern one claim from another. If you hear the term "EMF" and do not understand the equations, theory and principles behind electromagnetic radiation, this review is your warning. If you are worried about being taken for a ride by people taking advantage of your concerns, then you need to pay attention. My opinion is that this product is junk, and there is no documented principle of physics that even comes close to supplying a rationale for its claims. Zero. Nada. Zilch. Full stop. Check the pictures. There is literally nothing there but insulating goop and a cheap plug. Nothing. They are not even trying; they are just taking your money. I am obviously in the wrong business.
