Why controllers of Ereada® mats do not have a metal sensor to remove EMFs?
Some made-in-China pads have controllers with such sensors. But the only “EMFs” you can take away by touching this metal sensor is the static electrical charges which are not dangerous.
Ereada® Controllers are equipped with an active AUTO EMF elimination system catching them by special electromagnetic interception layers in the mat and directing them to the ground plug of a wall socket. It works like a real Lighting Rod.
The majority of “made in China” mats are not even grounded.
