Review on Dinggsun RJ45 Coupler 10 Pack - Blue Ethernet Extender Connector for Cat7 Cat6 Cat5e Cables - Female to Female Adapter by Bam Reeder

Great connector, but the metal connectors on one end that touch the connectors are bent in the wrong place. When I connected I had no internet connection. Luckily I was able to straighten the connectors with a magnifying glass and a safety pin. It was a little tricky, but I positioned and connected them correctly and had a good internet connection.
