I often feel overly stimulated by my devices. It's as if they have their own particular atmosphere, like one's had is in a diving bell and that there is a high pitched whine that is just out of audible range. At night they're always turned off or on Flight Mode because they emit EMF's that disrupt my calm. I noticed an immediate muffled effect as soon as I put the Shungite on my phone. It was incredibly easy to apply, it doesn't get in my way and it shuts down the uneasy whining that my phone used to make. I even feel safer carrying out around in my pocket now.
