Worked as described
My Phone/Broadband socket and hub was one side of the room and all the av equipment was the other side of the room linked by a 10m RJ45 Ethernet cable. I ordered 2 of the connectors for either end of the Ethernet cable so I could move the router. There were no problems with the adaptors and all the equipment is now in the same cabinet with no change to data speeds, I could also get rid of the Ethernet switch I was using so less clutter. Well worth the outlay

Great support through thick and thin thanks Fuzion
I ordered these so I could use a spare ethernet cable for my Internet connection after my original RJ11 connection malfunctioned due to the wear and tear of twenty years. These connections worked perfectly when I finally connected them to the right cable. Fuzion product support were very halpful they did what they could and I was very abrasive but the problems I experienced were primarily of my own making I feel that I apologise to the support staff of Fuzion for my continued negativity....

Essential part to plug my landline phone into broadband router
Had to order this to be able to plug my landline phone into broadband router following upgrade to full fibre system, as Vodafone did not supply it to me when installing the new line - though they did reimburse me for the cost subsequently.

Did exactly what I needed them to do
Purchased a pair to extend the modem cable from the socket into network rack where the modem (PPPoA to PPPoE) is situated and then on to the firewall/router. As I already had Cat5e cable in place, this was the obvious solution. Once they arrived, I plugged thme in and it was all working as I wanted in a very short time. No problems since then - a very simple solution

Was faulty and returned it. Still haven't received any refund.
Both the adaptor and the cable were faulty. I tested it with my old working adaptors and cables. Sent it back more than 1 month ago, still haven't got any reply. It's really cheap, so the refund doesn't really matter, but it was a huge inconvenience. I wasted so much time on it for basically nothing. It took ages to arrive, and then it turned out to be faulty. Should have tried local stores before ordering this one.

Just the job
Worked perfectly to connect an old tannoy system to a VoIP ATA.

Fits my sky hub
I use this to extend my Internet from my front room master board to my craft room, I use in conjunction with another cable though as my other cable is to large to fit in my hub

Thought this would do the Job, but it didn't :-(
In resolving a cable connection issue, Openreach replaced my existing socket with a 'new' NTE5C mk4 master socket. This has an integrated filter and features separate sockets for phone and broadband connect. I purchased this adaptor in the hope of using a 'proper' network cable (cat7) to cover the distance to my router, rather than the cheap RJ11 cable hoping it would improve speed and reliability. So RJ45 cat7 cable from the NTE5C mk4 faceplate to this adaptor, then the short RJ11 end into the Modem/Router. Unfortunately, it didn't work :-(( I'm unsure if the faceplate has been wired correctly or if the issue is with the adaptor... Have gone back to the RJ11 cable.
