Blocanopy EMF Protection Anti Radiation Naturell Dome EMF Shielding Canopy (Cal King 84" x 72")

I already returned this product because it is a complete scam! I put a tiny cheap radio into it and the music barely playing was not diminished in the slightest. I DO own some emf-resistant fabric called copper-nickle rip-stop and that material DOES kill the signal to any music station on a radio. I am STILL looking to buy an EMF canopy but this company fought me constantly and did not want to refund me until I filed a complaint with the credit card company and SUDDENLY this company found my product and agreed to return it!I am not a fan of lessemf.com site either, where I bought my nickle-copper ripstop material though, because they also sold me an 800 dollar 'quiet zone retreat' that did not reduce EMFs. I am looking for another place to buy emf resistant material. If someone knows an honest place with decent return policy please let me know.I might just have to build a faraday-cage out of metallic door screening, wood and snap-together magnets from the local hardware shop like a couple on youtube did when building their own EMF enclosure for their bed.
