It is recommended that your children have the smart DOT EMF blocker with them at all times. With the product with them, not only will it help strengthen their biofield, but it will shield them from ambient Wi-Fi, 4G and 5G emitted by any wireless devices around them. Ideally, the product should be placed on every wireless device they use or are being surrounded by, as the smartDOT radiation protection device is designed to retune any radiation emitted from these devices directly at their source.
