The Penta Power Tags work exclusively on the scalar part of the electromagnetic wave, whatever the frequency this wave has. They do not touch the electromagnetic component of the radiation. Your appliances continue to work as well as before.
The Penta Power Tag technology, based on the findings of Prof Dr Konstantin Meyl, generates a positive (scalar) field. This field transforms the possible damaging component of all forms of radiation for people, animals and plants. This technology is a form of passive quantum technology.
