An average car nowadays contains 4000 to 8000 meters of cable and wiring, not including on-board electronics, GPS and Bluetooth for hands-free mobile and smartphone use. At the same time, cars act like a "Faraday cage" which may further increases the radiation exposure. Therefore, particularly frequent drivers report about typical discomforts such as loss of concentration, fatigue and tension. For these individuals the GREEN 8 GOLD® Car Harmonizer was developed. It may neutralise the radiation in the car and facilitate a relaxed, unencumbered driving experience.
