Network Ethernet Cable Tester for LAN RJ45 Cat5 Cat5e Cat6 Cat6a Cat7 UTP/Shielded Cable and RJ11 RJ12: desertcart.com: Industrial & Scientific

Review: Ethernet Cable Tester - Great tools, easy to use. Performed flawlessly. Great price.
Review: Worked great and inexpensively resolved my problem - Worked great for finding which Ethernet lines ran throughout my new home. (Builder did not label any of the drops). Can easily do with one person. The instructions, as written, were not clear, but if you just connect the "remote" to room you want to test, the main unit will light up when you check the other end -- it's easy to figure out yourself. Worked great.

### ⭐⭐⭐⭐⭐ Ethernet Cable Tester

### ⭐⭐⭐⭐⭐ Worked great and inexpensively resolved my problem

### ⭐⭐⭐⭐⭐ For under $10 I have the zero complaints
*by S***I on April 10, 2025*

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.
