~ Diamond Form Faraday Fabric ~ High-Shielding Signal Blocking ~ Blocks RF Signals (Including 5G) ~ 54.5" Width by 5 Yard (180") Length

I tried this by just setting my phone inside the fabric completely covered. It blocked the signal. I have not used it yet for its intended purpose as it showed up late while I was making my first project. I had to move on without it.

I brought this fabric to cover my lod desktop computer that was causing interference to my indoor digital TV antenna. I brought a new system later and no TV interference however the fabric helps to reduce cell tower 4 and 5 G signals to my room and made my Tinnitus worse. After putting up the fabric to bedroom wall, my Tinnitus became less bothersome.

I use my 5G hotspot for internet. May change that soon! Wrapped my phone in 1 layer and lost signal. Tested 2 layers of copper infused bed sheets didn't loose signal. Copper infused gloves, didn't loose signal... I added a layer of this material to my phone case but since it is not a complete wrap, I still get signal, but hope to protect my phone holding hand.

seems like its good for what i wanted

I placed this sheet under my office window because my cat likes to sit there looking out the window when I work and the EMFs were high because the electrical runs there. After applying the EMFs were at an acceptable level. Good product!

Purchased for bag making. Tried to block cell phone. I could not get it to block. If there is a method to use product then instructions need to be included. Product was returned. 3 stars goes to company because customer service is honorable and return accepted without question.

Put it in a window between outside elec.meters and room to stop rf signal. It seems to have done what I required.

The fabric works really well in handling EMF's and other annoying energy flows in my surroundings. Great to get something that actually works
