Klein ToolsVDV526-200 Cable Tester, LAN Scout Jr. 2 Ethernet Cable Tester for CAT 5e, CAT 6/6A Cables with RJ45 Connections

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.

This is a really nice tool. Yes, it's more expensive than the cheap Chinese ones with limited feedback. But, it's worth every penny. I've used it for cable runs up to 150' with no problem. Claimed length is far more, but I can't comment on that. I can say it reliably detects opens, shorts, miswires, even split pair miswires. Zero fails diagnosing a wiring error. Love it.

A must for long cable runs. I ran 100’ of Cat 6 to access points in my house, and couldn’t figure out what the issue was. Connecting this to both ends, I found that a single-wire termination failure was the issue

If you’re a professional in the information, technology field and plan to use this device on a regular, then get yourself a proper fluke tester.With that statement out the way. For your average home, user/amateur this is more than enough to test your data cables. The device is simple to use and from what I can tell so far it’s been accurate. I can find no fault to report as of this moment. The device just works and does everything as advertised.

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…

Great Ethernet cable tester. Small size. Works well.

Works well. Time will tell.
