Heka Naturals Shungite Mobile Phone Plates | Adhesive Phone Stickers Made of Authentic Shungite Stones to Use on Your Mobile Phone and Other Electronic Devices (Set of 3)

Blocks signal so completely that it is almost impossible to send or receive anything on your cell phone ever again.

Todo ok

leider ist der Rand der Steine abfärbend und daher nicht für Handy und Co brauchbar!

Lovely weight of shungite, which fits neatly under my phone cover

These Shungite stones actually focus and amplify the electrical leakage emitted by my phone to the extent that my hand hurts after touching my phone for a few seconds (it used to reach pain touching the phone after several minutes). This actually makes sense once I thought about it, Shungite is a good conductor of electricity. If you are also sensitive to this extent, I would not recommend this purchase. I plan to now buy some sort of insulating material instead to stick over the magsafe part of my iphone case, which I hope will help more. Most people do not feel the electrical leakage from mobile phones (including from my phone), which might explain the good reviews. The stickers on the back of the stones are not strong enough so they needed an additional purchase of strong double sided tape if you do decide to use on your phone anyway even though it will make matters worse.
