iwillink 10Gbps CAT7 Coupler RJ45 Keystone Shielded Coupler 10-Pack, Ethernet Coupler, Female to Female Keystone Jack，STP Keystone Insert for Cat7/Cat6a/Cat6/Cat5e Cable

I got these to replace the keystones currently in use because one tested as bad when I was suspicious about the connection speed light on the switch not as expected. More might also be bad which would explain other slower connection speed lights so I'm replacing all of them.I tested all of these with a cable tester before installing. None were defective. These are physically smaller than what they replace so they are easier to install in a 6 port wall plate than the old ones. The connections are snug. No issues. No complaints. No reservation about recommending them.

This coupler was tested and works up to 10GbE connection verified. No issues with connection been in use for nearly 1 month no issues with connectivity it is shielded as advertised. It is a good product although slightly expensive. Have only used as a coupler have not placed any in keystone plates.I will note that my CAT6 coupler also allows for 10GbE connection and they were much cheaper but not shielded so something to keep in mind both items work to provide the same connection so unless you are in a spot where things are critical and need shielding for your jack I would consider these things when making a purchase.But the quality of these seems a bit better than the Cat6 plastic connectors there isn't as much play in the connection. So this to me makes it worth the extra money cause the plastic ones have play which may cause disconnection if pulled or hanging easily solved with some electrical tape or zip ties but still its nice to have a good connection. I will buy again as needed if available.

Worth it for the price. Has the speed and connectivity it claims it does. It was easy to install on my Ubiquity rack, and the size of the blocks was a little bigger than I thought, but allowed me to connect and disconnect wires from the back with little to no effort.

These work well, and i get consistent throughput on them. that being said, the quality feels a little on the chintzy side. cheaper really thin sheet metal for the housing,and when installed in a keystone panel for a rack the pressure on the cables warped them a bit (and there wasnt much pressure) 4 star because they at least work fairly decent.

This really improved the look and efficiency of my network. Really pleased with how it turned out.

Seems like a good and solid coupler.

Its a great fit for my topgreener inserts and looks fine. Easy to click in and take out as well. Used it on a three port and all fit perfectly fine .
