Despite the use of shielded connectors, the manufacturer has skimped on the cable itself; None of my cables passed the screen test with my cable tester. For my purposes it didn't matter because I'm going to literally cut off one end of the cable and use it for a custom adapter that has nothing to do with ethernet (although extra grounding might be nice) but if you see the metal ends and expect that it is a shielded CAT 6 cable, you will be very disappointed. It would be better if the manufacturer A. shielded the cable properly, or B. used an unshielded cable just made of plastic so that it doesn't look shielded. An unshielded cable that looks shielded is potentially problematic in many situations, and you should never route cables this way.
