Radiation Blocker
Sticks well on smart phones and looks good too.

This is a quack product. It will not block, prevent, stop nor reduce any radio signals.
I have not purchased this product, but no one else that has written a "positive review" so far has either. I am not sure why Amazon keeps allowing these products on their platform that are such blatant and obvious scams.These 5G "radiation prevention" stickers don't do anything. 5G is the weakest kind of mobile phone signal, which is why they need to have lots of little towers, rather than one big one as is common with TV and 2G signals.5G uses the same frequency as WiFi networks. These stickers might even make more of the signal area hit your skin if you put it on the back of your phone, the tiny metal area will reflect and concentrate the signal towards the front of your handset where you are looking at it.A tiny piece of metal will not prevent any RF signal and even if it did, you wouldn't be able to use your phone as a phone or use any of your WiFi devices.Microwaves operate at the same frequency as 2.4GHz WiFi, however WiFi only operates at most 100 milliwatts. A microwave operates at around 700watts (7000x more powerful), but they are safe because they have a protective grid around them to prevent the 2.4Ghz frequency wavelength from escaping from the case wedged between the two pieces of glass. The rest of the case is also an insulator. 5G operates between 5 and 6 GHz, a different frequency spectrum, but the newer style WiFi networks also operate at 5Ghz, but with even less power.The 'risk' of RF radiation is that it has the potential to heat your skin, but as the body is very effective at regulating changes in temperature, you would have to have your WiFi router or phone right next to (touching) your face for over 24 hours to increase your temperature by half a degree from RF signals. You are more likely to get warmer by the heat of the power supply than you ever are from RF signals.If these products truly work, then it would be fairly simple for a company to provide the data to show that they are working under a scientific test, however they just want to take your money.RF signals are safe, there have been no increases in the amount of cancers due to mobile phone use since they were invented.

A made up technology with no real use scenario.
This will not block 5g signals, nor give you any health benefits. Amazon shouldn't even allow it's sale. A complete waste of your money and dangerous sudo-science.
