Pozitron Plus Mobile Phone When used on your phone, covers you up to a 1m radius. It can be placed between your cell phone and the cover. It can also be placed between the battery and the back cover if you don’t have a protective cover. It is a great neutralizer of the pathogenic specter radiating from repeaters, radio waves, and strong electromagnetic waves that the mobile phone battery also produces during phone conversations. It’s also extremely beneficial for children/youth, who are being raised in this technology era. They are constantly exposed through their cell phones and computers when working, on social media or gaming.
