RJ45 Cable Tester Network Cable Tester Ethernet Wire Test Tool for LAN Phone RJ45 RJ11 RJ12 Cat5 Cat5e Cat6 Cat6a Cat7 UTP/Shield Cable

Worked as described. Was able to locate and test an ethernet cable.

Suddenly my router stopped working...fortunately with this tool I could identify it was the wired connection that was at fault instead of replacing the router I was able to replace the wires connection...all set. What an inexpensive & helpful fix. This is easy to use, points the IT sleuth in the right direction, & saves time & money. Also compact & solidly made. Stores easily. Great tool.

I've had a network cable tester for years that is built like a tank, but lacks the remote feature this one had. I had a network jack in the house that wasn't working and needed a tester with a remote to find the fault or else resort to trial and error fixes. This tool quickly identified the issue and I was able to quickly fix the problem. If that was the only time I use it, it still paid for itself in the time savings. This one isn't built like a tank, but the price is right and it got the job done. The network connectors were a nice bonus.

I bought this because I have 6 Ethernet cables that run under my house between 2 rooms and I needed an easy way to tell which Ethernet cable ends matched up. It turns out this thing helped in another way! After I labeled all the cables using this tester, I ran one more cable to connect a brand new router and satellite unit. Since that cable was a different color, I didn't need to use this tester. The main unit would not recognize that the satellite unit was plugged in. I thought the router might be bad and was ready to box it back up. Then I thought, this tester might tell me if the cable is bad. So I connected it up and it was! The brand new cable was faulty. This thing saved me a lot of time troubleshooting and potentially having returned my new router setup.

Summary: Replacing a previous unit I purchased at CompUSA 25+ years ago for 3x more money. Gave up wiggling the old one to get it to send a signal down the cable. Combine that with the only having LED's on one side I had to always run back and forth between the devices to make sure things were working- total pain. Broke down and got this one, what a great purchase. Packaging, excellent. Not over packaged, little waste, all can be recycled. 5 stars. Design: Simple, clean. 5 stars. Case: Honestly, I appreciate there is not one, I have the case from my old tester which is the same size, much less so many other cases over the years. Less waste as its unneeded. 5 stars. Functions: Works well, clear indicators. The only comment I make is that the S isn't Slow as you will see in my video per the documentation. S is "Speedy". 4.5 stars. Ease of Use: Simple. 5 stars. Overall, I'm really happy with this product and wish I had gotten it sooner. The 'Speedy' functionality + LED's on both sides are a life enhancing feature for me. I used a bad cable in the included video to show something different than a good cable pattern like in most videos. You can also see that changing it to S isn't Slow, it's Speedy.
