AfterDark. EMI protective MAT for RJ45 / USB

These are cheap plastic with a stick-on metallic pad. Half of the pads were falling off. I would be afraid to use these as the metallic pad would fall off inside my equipment and short circuit the unit. On top of all this, the shipping was overly expensive and DHL billed me another $60 for import duties. All in I spent over $110 for something I cannot use. Buyer beware.
