After extensive research on electromagnetic field (EMF) radiation, we have developed a patent-pending, easy-to-use, freely interchangeable piece the size of a credit card that fits between your phone and its case that blocks harmful radiation without interfering with the phone's antenna. Simply place the Blocker between your phone and its case and start shielding yourself immediately. It's like wearing a lead vest for an X-ray, except for your phone.
One Blocker lasts a lifetime! Instead of designing a case or an adhesive, we created our Blockers to be interchangeable with most smartphones and cases. Rest assured that you will be protected from EMF without defacing your phone or interfering at all with the normal use of your phone.
