The QuantaCase® incorporates world-renown RF Safe® Radiation Shielding Technology, which has been lab-tested to show electromagnetic radiation, including 5G frequencies, is reflected via conductive shielding fabrics in the front cover.  In addition, the QuantaCase has an exposed RF Safe® notch where an inexpensive Ohm meter can be used to test the conductivity of the microwave barrier between your body and device!  Unlike most products that require expensive microwave meters to verify what is inside, the highly conductive RF Safe® shielding fabric inside the QuantaCase® is accessible for easy conductivity testing.
