i used it to wrap around my cell phone when not in use (in order to avoid emf exposure). It did work for the intended purpose because when the phone was on i called the phone from the landline and the call could not come through.
To those that say that it didnt work, I would like to say that in order for it to work I needed to completely wrap the fabric around the entire phone in layers (at least 3 layers). Also, I attempted to simply lay the phone on a hard surface then drape the fabric over it....but the fabric did not work this way and the call still came through. I know that it isnt explained this way on Amazon (which can be frustrating) however the fabric does work appropriately when used the way I am describing. Also over time the fabric will degrade making the fabric useless. For me it lasts approximately 4 to 5 months.

The reason I gave it only 4 stars out of 5 is because it now takes up to 2 months to recieve the item after ordering.... it used to take 2 weeks to recieve after ordering. I dont know why it would this long.

Thin but powerful. I lined a few things with this stuff and it blocks key fobs and phones. The tape they send is about 18 inches and its not very sticky. I bought copper rfid blocking foil tape from another company to tape some joints. I would recommend a double layer for better phone blocking. Its not sturdy as I want it to be so I recommend lining your bag or box with this then a layer of some other cloth or shelf paper etc.. to protect it. 5 stars would have been given if they would have managed great blocking with one single layer. Overall I would still recommend it

I was skeptical. So I made a pouch, put my phone in and had my wife call me. My phone didn't ring and wife said it went right to voice mail. Nice. Now, feeling confident, I made a wallet and lined it with the copper fabric. With one credit card in it, I tried to scan it at the gas pump. Wouldn't scan. Put the same credit card in an unlined wallet and it did scan. Did a similar test at the grocery store. I now feel confident that the copper fabric lined wallet will protect my credit cards from close proximity scammers. I plan on making lined wallets for the rest of my family.

I put a strip of this at the foot of my bed so that my bare legs are in constant contact all night. It helped me the very first night, 2 years ago, and is still working. The sheet is large enough that you can cut it in strips, no need to lie on the entire fabric, any small piece of grounding fabric should be enough. I taped the cut portion with aluminum duct tape to prevent fraying. It has never abraded my skin, I don't even notice it. Well, I do have minor leg neuropathy from cancer treatment, so maybe your legs will be more sensitive. There are tons of workarounds to ground yourself at night. Grounding overnight means I awake, get out of bed and spend the day not groaning about aches and pains unduly. Just try it! You've little to lose but your pain. p.s. I do not use it for shielding.
