I have been using the 5G-EMF-Guard for nearly six months on both my laptop computer and my cell phone, and from the very first day, I recognized I felt more peaceful and inner quietude after using them, regardless of the amount of EMR emanating from either of them. In other words, I noticed—and continue to appreciate—I'm significantly less affected by my devices' subtle electrical intensity, compared to how I felt before. Even after working for five or six hours in a row at the computer (I'm a book editor) or being on the phone for literally an hour or two, I don't feel any build-up of the EMR energy I've typically found associated with such long stretches. I'm both grateful and relieved to have found these products.
