DefenderShield® EMF 5th Generation Wireless Emission Radiation Protection Shielding Scarf - One Size for Men and Women

I have an EMF meter, this scarf blocks 100% of the radiation from my devices (laptop, monitor, keyboard, mouse, etc). I get around 200 volts per meter from EF radiation alone in my chair, this scarf blocks it to 0. Awesome.

I LOVE this scarf! It eliminates the pain I get in my neck and chest from EMF exposure when working on my computer. It has allowed me to work again!

I wear this often on my body when working on laptop, even at a desk. I have measured the fabric and it blocks EMF very well. Recommended!

I actually returned the scarf. I had also bought an EMF meter to check out all devices in my house that put out these currents. When I put the scarf around me and the meter under the scarf, it did indeed block out the EMFs from my laptop. However, when I put the scarf (folded up into several layers) underneath the laptop and put the meter under my desk (just as a test), the EMFs emitted registered very high. I also found that if I sit far enough away from the screen without the scarf, the meter registered very low EMF radiation emissions. And since I don't use my iPhone very often and keep it on airplane mode AND in a Faraday case, I didn't think I'd wear this scarf much. I also found the scarf unwieldy and because it was polyester, I didn't like the feel of it as I prefer more natural fibers. I also thought the price was quite high. However, all that said, I think that perhaps some people who are extremely sensitive to EMF radiation, might benefit from wearing this scarf.

This product does not effectively block, or even reduce, magnetic radiation. I have a TriField TF2 meter and the fabric does not do anything to reduce the magnetic radiation from an electric induction stovetop. It's terrible. I wish I could get my money back.

I work for a company that does radio spectrum monitoring (I help write the software). I'm not a hardware guy but due to covid lockdowns I do have some tools at home to test the software with, including a radio that can measure signals from 50 - 6000 MHz. I figured I'd give this product a go thinking it probably did nothing. Surprisingly, it works and you can easily verify some of it from the comfort of your own home.Test 1: Using my car's remote key fob, I pressed the lock button and found it on the spectrum at about 314 MHz with a pretty strong signal around -75 dBm. I wrapped the fob (and my hand) thoroughly in the scarf and pressed the button again. No signal detected at all, with the antenna being only about 6 feet away. Test was repeated several times. The scarf was blocking the 314 MHz signal entirely.My radio is too big to wrap the whole thing up to see if it then sees nothing but the next test you can easily try yourself if you have an Android phone (maybe iPhone has the same readouts somewhere) --Drag down from the top of your phone and press the "gear" icon for Settings.Tap ConnectionsTap Mobile networksWatch the "Signal strength" lineI normally sit at about -82 dBm for my cellular signalI put the scarf flat over my head and kind of made a "tent" for the phone in front of my face. Ideally you want the scarf to be 360 degrees all around the phone, including through your head, since radio signals can bounce and come from anywhere.I watched the signal strength go down to about -120 dBm which is right near "no signal".Also do the same thing with the wifi screen, which doesn't show signal strength but you can see all the bars go down and detected wifi networks blink out if you've covered up well enough.Conclusion: it actually does work. I don't have the stuff on hand to test the full range (and also while Vine gives me the product for free, I am not paid to do the review, do not have to give it a positive review and am too lazy to test it much further except for personal entertainment) so I'll just say "they didn't lie, it's not just a piece of cloth, it does definitely block a noticeable amount of RF and you can pretty easily test some of it yourself." (Test 3: Put it over my wifi router but like I said, too lazy. Also, I should probably get back to work...)I will say, though, as a guy who works in RF technology and has a big radio in his room, I don't think you need this protection and there are no known vectors by which a non-ionizing radio frequency (including "5G") can cause health problems but if you're worried, here ya go. It is also a very nice scarf. It got quite warm when it was over my head.You could wrap your car's key fob in it at night though, if you were worried about hackers using a repeater to unlock your car. That's a thing. Not a common thing. But a thing.

This is a Faraday Scarf. The job of a Faraday blanket or scarf is to cover the body to protect you from EMF, radiation. This is effective, lightweight, easy to wear, easy to fold up and store. I've been using it when I go out and am very pleased with it. Essentially, this blocks the radiation that can reach your body from various forms of technology, including devices being carried by other people, and I have found this to be a wonderful addition to what I use to prevent damage from being done to my body. Good luck in your search. I highly recommend this product and this brand. We love DefenderShield in our family.

Not sure if I notice the difference. A bit pricy.
