Klein Tools VDV526-200 Cable Tester, LAN Scout Jr. 2 Ethernet Cable Tester for CAT 5e, CAT 6/6A Cables with RJ45 Connections

I knew some of my CAT 6 ethernet cables had been wired incorrectly, but I did not know what the exact issue was. I ordered this tool and a crimping set and taught myself relatively quickly that there is an order to the color coded wiring, the RJ45 connector needed to be connected a specific way, and I solved 15+ bad connections in an evening.This tool allows you to see if a wired ethernet connection is correct, if not it gives you a "fail" message and includes the numbered order of the wires, allowing you to see exactly how it was wired wrong.I thought the tool was fairly expensive, but considering it saved me a call to an electrician, I would consider it worth it. And now I have a new skill. Good investment and great product that worked as it should right out of the annoying blister plastic wrapping.

Why did you pick this product vs others?:A bit pricy but works well.

Easy enough for a 9-10yr old to test wires, display is easy to read, simple functions that work, small and light so fits in a tool bag nicely. It’s a Klein tool, they just work, it’s not my first Klein electrical tool and won’t be my last one.

Really easy to use this is my second one i have purchased. Great product

We had an Ethernet wall plate with two Ethernet jacks relocated to a different place on the wall. Subsequently, we noticed that one Jack did not work at all, and the second one had really poor performance. With this Klein Ethernet wiring tester (the Jr. version) we identified the wiring pairs (3) that were not making connection and re-punched down the wires. We are back up and running. This Klein Ethernet tester was simple to use and solved our problem. It is well engineered/designed, and It felt sturdy like a quality product.What is the reason for one less than 5 stars? Well, it is a minor thing, but did cause some a little concern. When the unit arrived at the house, it was sealed in one of those packages that requires destroying the package to get the unit out. The unit and its packaging appeared as a new, off-the-shelf item. The first step in using the tester is to pull out a small tab to “activate” the batteries (2X AAA). The tester did not turn on. I opened up the battery compartment and noticed one of the batteries was installed backwards (the battery + end was up against the spring). I reversed he battery, closed the battery compartment and all worked perfectly from there. Was this the result of a returned unit or an assembly issue? Either scenario deserves one less star…

Tested it the past two days, worked flawlesly. Worth the price.

Thai scanner has all the tools I need for checking cat6 lines. One thing I wish it could do is measure length.

very good quality. Best value for the money. Klein Tools is my go to!
