Review on InstallerParts CAT6 Ethernet Cable - Red, 0.5FT, 10Gbps, 550MHz - Professional Series for High-Speed Internet by Dana Mahendra

Either nobody knows how to test them or they have other cables. First, the cable is 8-1/4 inches long and the housing and connector extend it to 11 inches. The cable can't be Cat 6, the twist is ALL wrong, hardly conforms to Cat 3. Finally, and that's why I love these companies, no speed claim is possible with the structure itself: Tested with Fluke Reporter, I can't even at 11 inches overall more than 340 MPS, which is correct in category 5E. It would be a lousy Cat 5E cable, let alone Cat 6. Don't buy it. Let's see if the seller is honest enough to give me credit.
