Ethernet Cable Tester
Great tools, easy to use. Performed flawlessly. Great price.
C**.
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.

For under $10 I have the zero complaints
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.

Light Weight Inexpensive
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.

A must for any cable creator
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.

Don't waste your time with this
Here is your reminder that you get the quality that you pay for. As this item is nothing more than a simple continuity tester, I opted for the cheapest option that I could find. The item quickly arrive in a sealed bag with no physical damage noted. I installed a battery, connected a fresh RJ45 patch cable and started the test. It began sequencing through the pins until it skipped #4. I tried a secind cable that i made and same issue. I tried several brand new out of the manufacturer packaging cables with the same results. Fortunately, Amazon makes returns easy.
