This LAN tester works well for testing patch cables and in-wall network connections. It can be used for RJ45 and RJ11/RJ12 connections. I tested it on an Ethernet patch cable I hand built and it worked well. It discovered a crossed cable that I hadn't intended. I will have to re-crimp the RJ45 connector to correct the issue.OperationTo test a patch cable, you plug in one end to the transmitting unit and the other end to the receiving unit. You then turn it on and the signals on each wire will cycle down with illuminated LEDs. For a pass through cable it should light up 1-1, 2-2, 3-3, etc. (see photo). You can easily spot an intended or unintended crossed wire if it shows for example something like 3-5, or 2-7. There is a slow mode that slows down the cycling so you can get a good look at the pairing of the LEDs.Two small patch cables are provided for insertion into a receptacle for testing a long cable run.It also comes with a convenient carrying case that has a belt loop.Build QualityBuild quality is acceptable. I wouldn't recommend this tester for hard day-to-day professional use but it should work well for a DIY tester. Each LAN port has a vinyl insert to protect it from dust. Unfortunately, these are not secured by a hinge or strap so they can easily become separated from the main unit. I removed a star from the review for that.Ease of UseUsing the tester is a as simple as plugging in your LAN connection and turning it on. The LEDs will then begin to cycle to show you each wire's connection. It is very easy and intuitive to use.RecommendationFor the DIY user this is a great tool. For those users, I recommend this tester.
