This new multi-wave scalar waveform configuration offers the best protection to date from radio frequency radiation and 5G. Some people will experience a minor detox while initially using this product, and some will not (I have! Check out my vid here). This may be due to the release of stress on the body from EMF and also the immune system may normalize. One Cube is recommended per home or Office with very high EMF. Homes or Offices within 1km or line of sight of a cell phone tower, smart meters or a large number of Wi-Fi routers. One cube is recommended for each floor for high rise apartments, work place and schools. Coverage of 90m in all directions. Also check out their Tesla Portable model to carry with you when you are away from your home or office, this will maintain a level of protection.
