It’s a little tricky to write a review on a product like this without equipment to test EMF levels, but anecdotally, it’s made a noticeable difference for me. I use corded headphones for most calls, but on the occasions when I’ve used my iPhone 12 without them, I used to end the call with a slight headache. Since applying this sticker, that hasn’t happened, which I take as a positive sign.I chose this product because I own an iPhone 12, the same model that received media attention in France for radiation levels. I'm not ready to upgrade, especially since my phone still works perfectly, but I did want a bit of added peace of mind.The product arrived quickly, feels sturdy, and seems well-made. It has an adhesive back and fits neatly behind my phone case. My only minor concern is that it’s quite firmly attached, so I’m unsure how easily I’ll be able to transfer it to a future phone. That’s the only reason I’m giving it 4 stars instead of 5.Overall, it’s a fair price to pay for peace of mind and for me, that’s worth quite a lot.

Good service, Good product, Easy to Use.There is no equipment to test the radiation lever, I hope it is effective.
