Cyber Faraday Fabric RFID Shielding Silver Fabric Roll 62" x 3 Ft. - Premium Grade EMF Signal Blocking Material

Took four to six folds all the way around iPhone to cut cell signal. No proof of authenticity. Not knowing really if product is as says. Not enough product information. I except an email from Faraday.

This fabric really helps with emf and ehs (electric hypersensitivity). I cover \ wrap \ use my fabric day and night. I use two layers sewn together in a hood to cover my head at night and use the rest to cover my body so I can sleep and not toss and turn all night. very helpful.

Great Protection. Don't know what I'd Dow without it.

Works great! I measured under 1 ohm with my multimeter probes a few feet apart. Wrapped a single fold around my phone and watched the bars drop. No internet. No calls. Nothing.I saw another review claiming 4 folds didnt work and I laughed; he probably didnt understand how signalnstrength is a time averaged value. Drape this over your phone and call it. Wont ring.Fabric is softer and more flexible than expected. My fiance saw it sparkle and immediately wanted a dress made of this fabric.
