Amradield Conductive Faraday Copper Nickel Fabric for Smart Meter RF Blocking Plaid Ripstop Type 43"x39"inch with 2x20 inch Conductive Tape

It gets quite warm. I did not attach it to anything else, no grounding. Here is what I found: It provides some, uh, barrier, but the nickel causes a rash on one of my eyelids, so it should be attached into a fabric casing. The smell is not bad at all. You have to completely wrap it around as much of your head as possible, except the nose and mouth, with no gaps. It's very lightweight, like a scarf. Maybe I'll try putting it between 2 ski mask hats. Or set it over a cotton scarf on me. Evidently they say it is not washable. I wish it were easy to snap into a quilted cover.

I definitely have stopped hearing the voices in my teeth. It is a bit rough on my cheek but well worth it. Word of advice, do not drive with your head wrapped in this.

It does not work! I covered my router as a test run, and the signal only decreased by 10 decibels. I tried again, this time I doubled the cloth around it, still only lost 17 decibels, not even 20! | All I wanted to do with it, is to place it beneath the router and the sides of it. Was trying to create a blind targeted-barrier where I placed the cloth. Getting hacked, and was trying to block the signal from the direction I suspect the hacker to be located at. I even wrapped my cell phone within it... I used my girlfriend's cell phone to call myself, call came trough without a problem. Do not buy this product, it's a 'Rip Off!'

Based on rf/emf meter did not block out smart meter

You gotta wrap the heck out of a cell phone to block calls

Was told this worked well to block EF (Electrostatic Fields), it blocked absolutely nothing, not even 1% of the field. I cannot speak to how it does with RF or EMF, but if you are looking to get something to block EF, this is absolutely not it.

Useless. Like no effects AT ALL I have a EMF tester and the number didnmt change
