RJ45 Cable Tester

does exactly what it says it would, easy to use. Invaluable when laying and terminating ethernet cable. Needs a 9V battery not included.

For me this has been an absolute Godsend. I have many cables in my spare cable box and rather then have to test them randomly to see which still works I have been able to use this inexpensive device to check, which to date it has done reliably, leading me to bin the faulty cables with confidence. I have also used it to test cables when devices haven’t been working correctly to find that there has inevitably been a cable problem and having purchased an RJ45 crimping tool I can now reassure myself that the crimping has worked OK. I’m very happy with this purchase and wouldn’t hesitate to buy another.

This network cable tester is straightforward and very easy to use, even for someone with limited networking experience. The setup is simple: connect the master unit to one end of the cable and the detachable remote to the other. It quickly identifies whether a cable is wired correctly or if there is a break or fault, which makes troubleshooting far easier. The instructions are clear and simple to follow, which is especially helpful for those who are new to networking tasks. The device feels well made and reliable in operation. The only drawback is that it does not come with batteries included, which would have made it ready to use straight out of the box. Overall, this is a practical and dependable tool for testing network cables. It is beginner-friendly, accurate in identifying faults, and good value for anyone setting up or maintaining a small network.

Great product, had to wait for Ethernet cable I put together to see if this works and it did! it allowed me to see a mirroring error perfectly and enabled me to fix the cable. Great piece of kit and highly recommend. My hobby is to work on electrics, networking, cabling, tools etc and this is definitely one to add to the collection for any IT individual who wants to extend Ethernet runs.

This tester does identify cable faults. If you've made your own ethernet cables (or just renewed a plug) it will show if some wires aren't properly connected or if they're in the wrong order, but you do need to be able to see both ends. I used it to check a cable already in place between two rooms on different floors, so I needed someone to read out what they were seeing on the other end. It was a sequence error so we needed to be on mobile phones to discuss sequence we were both seeing. It works well and is fairly easy to use so is good value for money

Seems to work well. I think the biggest issue is me operating it. Although the documentation is helpful I didn't need to use AI to help guide me through the process

I paid an electrician for a full rewire including phone lines and network. Nothing special or complicated, just wanted to hardwire 2 tvs and an Xbox in 3 separate rooms. Openreach had to come out and fix the phone line and he checked the ADSL sockets for me, said it wasn’t going to work and that it wasn’t on his job sheet to fix. I bought some kit to refit the plugs and checked the sockets and it all looked ok to me. I saw DIY Guy on YouTube who detailed wiring in your own net at home and realised it was probably a problem I could fix myself so I bought this whizzy little gadget, checked the line to one of the tv screens and it showed two wires not working. On closer inspection with my phone on 3x zoom I could see why. Without this bit of kit we would still have needed to use WiFi and keep having to reset the tv. It’s all up and running now and I’m very pleased with this purchase. I feel confident enough to help my kids in their homes if they need. Useful as they’re both tech heads :)

A quick and easy way of testing network cables.

Einfach, preiswert. Funktion völlig ausreichend. Damit konnte ich die Verkabelung vom Keller bis in den Dachboden testen, korrigieren und es hat sofort funktioniert. Top!!

iyi

This cable tester works exactly as described. It’s simple to use — just plug in both ends of the cable and it quickly shows you if everything is wired correctly. It’s helped me identify a few bad cables and confirm my new Cat6 runs were good. The build quality feels solid, and the detachable remote makes it super convenient for testing longer cables in different rooms. It’s small, lightweight, and easy to carry in a tool bag. For the price, it’s an excellent tool for anyone setting up or troubleshooting home or office networks. Highly recommend for both beginners and tech enthusiasts.

As described.

Indispensable pour installer et tester un câblage ethernet ou téléphonique. Signale tout défaut de branchement (court-circuit, inversion de connexion, brin de câble sectionné). Nécessite une pile de 9V non fournie.
