Although these products are intended to reduce electromagnetic radiation, their effectiveness is usually limited or non-existent. This is because they only block a (small) part of the electromagnetic radiation and do not affect the scalar component that causes the very health problems . Penta Power Tags, on the other hand, transform exactly this scalar component.
A unwanted side effect of using radiation-blocking products is that your own devices, such as smartphones, have to work harder to connect to cellular network towers, causing they produce more radiation .
This also applies to well-insulated new construction homes with poor cellular reception . In such cases, wireless devices will have to radiate more to connect, resulting in more radiation generated .
