TitanRF Faraday Fabric - Pro Construction Kit XL 20 Yards - Military Grade Fabric Blocks RF Signals (WiFi, Cell, Bluetooth, etc.) - Dims: 60ft L x 44in W / 220 sq ft / + Free 20ft L Conductive Tape

We bought the Pro kit along with 50 meter roll in order to block out all the waves of our new home. The 50 meter roll was send over 10 days late so we started with the Pro kit and assembled these according to the directions. We tested the results and no change. When we tried to return both product, Ryan accused us of buying them so that we could return them and refused to approve the return even with the 50 meter roll unopened. Why would anyone do that? We just wanted a product that would shield the RF/EMF.
