Blushield is the only technology in the world that protects what is really doing the damage from EMF – the scalar information component. As long as we have electricity and wireless generated how they are, this undesirable component – which is what is really doing most of the damage – will exist. Passive devices (not powered – shielding etc) are unable to protect from this as the strong and powered detrimental information field is still going through. The information field even goes through a Faraday Cage.
Having the C1 Cube in your home, the mobile U1 when out & about, especially with your mobile phone and the Airtube which stops the microwave signal going to your inner ear (no speakers at the ear) is a safer way to live.
