Tatuo 1 Roll 1 Roll Faraday Fabric 79" x 42.5" Emf Shield Protection Emf Blocker Faraday Tape for Anti Radiation, EMI Isolation, Signal Blocking, WiFi Jammer

This product actually does work but you would need multiple layers. I still feel a little bit of energy coming through from the neighbors using this energy machine in my direction and sometimes go outside and use it. I have been beamed with energy for 7 yrs now and not a volunteer, this is like a some small laser energy machine, I don't know what it looks like; when I go to work- they aim it from their cars/ at home-next door--- it hurts not sure why these people doing this MOVIE cramp( NOT a volunteer )BUT it does help i have it around my house and around my stomach area mainly which feels like my spine is being crushed to where i cant lift boxes-- it does help

The thin fabric works extremely well. Had a friend try to call my phone and no signal went through. Exactly what I wanted.

The emf reading in my bathrooom that was opposite the wall where my Wi-Fi modem sits read very high, so I cut a piece of this fabric and tacked it on the wall by the modem. Voila!! It brought the reading down by about 80%. It is well worth the price. Hope this review helps.

First off, the material is relatively thin, but seems to be of a descent quality. Looks shiny like copper, and the resistance measured with an ohm meter between various points is less than .1 ohms. With the wifi turned off (to prevent any compensation in signal strength by the routers), I used the Ubiquiti WiFiman android app to measure the attenuation with the fabric placed about 18 inches feet in front of the phone. On average, there was a 10 db drop measured against three different Wifi access points. In the end, I folded the fabric in half (doubled it up) and hung it in the attic about 18 inches behind my TV antenna to reduce the EMI on Digital Channel 13. It actually worked, and the signal to noise ratio increased by about 5 db (which means less noise coming from behind the antenna).

Wifi everything is the same

I tested with an EMF detector and my Wifi router. The blanket blocks most of the EMF

I literally did a test with a EMF measured and IT WORKS!!!! I rent a partially furnished apt in there are some huge speakers from the 70’s in here. I purchased these to lay over the front of them in which the EMF levels were high, put this over that area and it literally lowered it. Thanks!

So I tried the putting my cell under a piece and calling it and it worked. No phone call. I plan to put in my purse and on my cell and over my wifi. There's plenty of it to do tons of projects to protect yourself. :)
