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.

Cheap and easy to use, it works great for testing RJ45 plugs. Saves a lot of time and identifies the exact cable 1-8 and ground for Cat cables. I have only used it on Cat6a and Cat5e so far but has worked great every time.

Amazing little gadget. It helped me to demonstrate to the Xfinity tech that my Cat6 was not damaged. The claimed that my Ethernet run was broken somewhere and my internet speed was affected because of that.

I like this product because it is light weight, easy to use, and for the small networking I administer, it does the job just fine. The quality, well it seems to be a quality item, however when you hold it in your hands it feels a little, well lets say too light. However, with that said, it's easy to use, easy to read, and does the job well for small network troubleshooting.

Why did you pick this product vs others?:Instructions were available and easy to follow on the website.

Great for testing network cables you make to ensure they will work properly when connected.

Works Great!! I would recommend this to anyone who is looking for a cable tester.Great price too.

Inexpensive, functions exactly like it’s supposed to. Perfect for around-the-office projects or as a backup to the more featured models.
