Review on 50 Pack Shielded RJ45 Cat6 Connectors - Gold Plated Pass Through Connectors with 3 Prong 8P8C Modular Plugs for FTP/STP Stranded Ethernet Cable & Solid Wire (23AWG) - Jar by Robert Kimble

These connectors look great but suck. I was only able to successfully connect 1 cable that supported a 1Gbps+ connection and every other connection I made failed and got stuck at 100Mbps. After about 10 crimps on the connector, cutting, and starting over, I finally went to Lowes, bought the cheapest and ugliest category 6 correctors they had, and PRESTO! The same cable that failed 10 times now had a 1Gbps connection. Save time, money and frustration and buy another connector. I'd love to return them but having burned about 12-15 of them I think I'm stuck on them.
