Bests & Worsts Reviews from Amazon

I test every RFID item I buy with the card reader I have at work. After the rave (and long) review someone put on here I confidently ordered them. I almost didn't test because of that review, but am so glad I did. I put my security card in one of the sleeves and voila, the light on the card reader turned green and the door unlocked. I was shocked given the thoroughness of the reviewer who was at a convention for security and swore none of his info was hacked while in this product. I have other products that protect my security card and the card reader stays red no matter how much I wave the card in front of the reader. I don't know what to say except these are going back and I don't recommend them at all!
