A word to the others writing negative reviews. If you're going to come across that way, please show us how you verified that it was actually NOT working for one, and shows us photos of why or at least explain to us why you think it wasn't working. People aren't in tune with what others are simply feeling, they need to verify. In our case, I checked our internet speed, and it went down by 600mbps, and our anxiety went down as well. If you're so sensitive that you're actually reacting to the fabric, then your modem isn't the only thing you should be thinking about. Depending on if you live in an apartment (which is in our case unfortunately) we are being hit by everyone else's 2.4GHz wireless that they may or may not use for any peripheral devices such as printers or scanners. We are also within 20-30 yards of 39 smart meters. So bear in mind there may be other things making you sick or anxious if you react that much to your modem.

I have tests to know if these things work. I put it over and microwave in the kitchen. Over the printer that has Wi-Fi. And cut it out for my wife to use over our child while feeding when she may have the phone in her hand. It will reduce the frequency and be greater when you are at distances. Until you are basically on top of the fabric.

This fabric was very thin. I had to double it over six times to block a cell phone. I returned this item.

I use this cloth to act as a groundplane for my portable antennas. It is far easier to set up than running a bunch of radial wires out from the antenna, easy to pack up, and is highly effective.

Product arrived quickly and is in very good condition. No idea if it actually slows or stops cell tower signal or other devices. But I’m satisfied with what I have. Thanks.

I tested this fabric in hopes that it would block EMF from some electronic equipment in my office. I put this fabric between my subwoofer and my GQ Electronics EMF Meter and it did absolutely nothing to block the high EMF coming from that speaker...ZERO help. I also tested it with my cell phone and it did nothing, once again. I am highly sensitive to EMF, RF etc and when I held this fabric near my body, I actually could feel an extremely negative affect on my body, including my heart itself... like actual pain. It was very strange when I noticed it the first time handling this fabric, but double checked it again a couple of days later before telling Amazon that I was returning it and it happened again.
