Review on 💡 Monoprice RJ12 6P6C Plug Round Solid: 50-Piece/Bag (107271) - A Reliable Solution for Your Connectivity Needs by Kathy Morgan

Purchased with a Trendnet 6P/8P crimping tool. Not sure if it's the outlet it plugs into, but they make a good connection when fully depressed and held, but when not depressed to allow it to come out to the end of its restricted range , 1 pair of wires was bad / no communication through my mating connector. Tried with solid round and stranded flat cable with the same result. Another brand - Networx 1xRJ11/12 6P6C from Revain - was 100% well connected with multiple cables so I will be using these connectors in the future. They "might" work for you, probably depending on the port they are plugged into. Compared to Networx, Networx has a slightly wider metal contact where they touch the mating connector.
