Network Ethernet Cable Tester for LAN RJ45 Cat5 Cat5e Cat6 Cat6a Cat7 UTP/Shielded Cable and RJ11 RJ12

My five-star rating is entirely based on the price and basic functionality. For less than $10 you are getting a continuity tester that sequentially shows which conductor matches the one being tested. Every other negative thing I write in here is solely for making others aware, or as ways to improve for the manufacturer.If your cable wires are set up 1:1 and it is miswired, the lights won't match. Sequencing through each pair happens quickly, but with enough time to see a mismatch and where.I think it does a few other things but I need to review the instructions more carefully as the small instruction set was clearly not written by a native speaker. The switch settings should be a bit more obvious on the housing. It should at least be printed with a few more words.That said, I deciphered enough to share that this isn't meant to be used while plugged into devices that are powered on. Another instance of wishing this was printed on the housing.It has both RJ45 and RJ11, so make sure you're plugging into the right place. As others have stated, these connectors are fiddly at best. If your cables have the retaining clip on the boot, they might be even more problematic.The housing material seems a bit thin, but the mold it seems decently executed, no rough bits or weird flashing.I like that the dovetail shoe helps keep this in one piece but also allows for split usage. That way you can at least leave the cable ends in place.What may also not be intuitive is if you have a known-working tester jumper, you can test two ends of in-wall wire after it's been installed. Of course, it should be tested first, but if it hasn't been this will at least save a lot of time.Overall, this thing is accurate and for 10 bucks, is durable enough to keep in my data wiring kit without worrying about it breaking.

Easy to use and it helps troubleshooting Cat5 cables. I had a few new installs where the cable was cut or damaged and this tester proved to the installer that the cables were bad.

I have a 100 foot ethernet cable that runs to my shed. it was easy to use and worked perfectly.

It's a very basic Ethernet cable tester. Need to test a cable? Here ya go. It works, is clear and easy to use, and has helped me diagnose some cable issues I've been having. It has no bells or whistles, just two modes, fast and slow. For the price and the functionality, it's hard to beat. The only reason I gave it 4 stars is because there appears to be even cheaper options, so it's not overly competitive in price.

Simple ethernet cable tester that works great!

Works great. Solved some LAN issues for me. Great price.

This is a great tool at a great price. Just remember to get a 9v battery. I ran 250’ of cat6 and was having problems with the signal from my router to the node. I suspected the wire was the problem and this tool quickly confirmed that. From now on I will be testing every cat6 wire I use to make sure it’s good. Very easy to use, even from 250’ away from the other end of the wire. Just plug it in and if all the lights light up in the correct sequence you’re good. If not, you have a problem with the wire or one of the connectors.

Easy and Quality together
