Details: The EMF Harmonizer+ from EMF Harmony supports your health and well-being as you are exposed to the electromagnetic radiation emitted by your cell phone or wi-fi router. It works by harmonizing the damaging energetic frequencies emanating from these devices, as well as by supporting your body against their effects. The Harmonizer+ is a small 1 inch x 1 inch metallic plastic sticker that you place on the bottom of your smart phone or wireless router. It is affixed with either the adhesive backing or a piece of the clear tape included. It can be used with a cell phone case. The EMF Harmonizer+ utilizes EMF Harmony s exclusive dual-level technology developed in Europe to support your health against the negative effects of EMF radiation exposure. The first level of action is a Direct Technology that harmonizes the negative energetic frequencies of the electromagnetic radiation emitted by the device it is attached to. The second level of action is an Adaptive Technology that supports your body as it is stressed by the radiation. The EMF Harmony technology does not block or alter the EMF activity of the cell phone or router, allowing it to operate normally. It is designed to provide you with much needed protection against the negative effects of electromagnetic radiation emitted by devices that that broadcast WiFi (wireless router) or use cellular communication (smart phone). It is compatible with and effective for the new 5G cell phone technology. For less powerful wireless devices such as a laptop, tablet, e-reader, or Bluetooth device, you should use the standard EMF Harmonizer, which is also sold on Amazon. The technology was developed in Europe and has been used and perfected over the last 30 years by scientists and healthcare professionals in Germany, Austria, Russia, and other countries. The EMF Harmony products are based on decades of research and practical application and their efficacy has been documented in many studies.
