Klein Tools 80093 Cable Tester, VDV LAN Kit with LAN Tester, Pass Thru Crimper, CAT6/CAT5e Plugs and Strain Relief Boots, 5-Piece

I first saw this Klein Tools VDV526-100 being used at jobs by other techs, and they all spoke highly of it — so I decided to get one for myself. After using it on several installs and troubleshooting runs, I can say I’m very happy with the purchase. This tester is a great option for checking network and LAN cables. It’s simple to operate but still powerful enough to catch shorts, mis-wires, splits, and continuity issues that cheaper testers often miss. One of the biggest advantages is that it comes with a remote unit, so you can test cables over long distances — even when the ends are in different rooms or buildings — without guessing or running extra trips. I’ve used it on CAT5, CAT6, and other common runs, and it consistently gives clear, accurate results. If you do network installs, maintenance, or troubleshooting, this is a tool you’ll find yourself reaching for again and again. Klein Tools didn’t disappoint — solid build quality and dependable performance. Highly recommended for pros and DIYers alike.

The Klein Tools VDV526-100 Network LAN Cable Tester has been a game-changer for my home networking setup. Whether you’re a professional or just working on DIY projects, this tester is a must-have for anyone dealing with Ethernet cables. The build quality is top-notch, as you would expect from Klein Tools—sturdy, durable, and designed to last. Using the tester is incredibly straightforward. It quickly identifies open circuits, miswires, and short circuits, saving me tons of time diagnosing issues with my Ethernet cables. The results are clear and easy to read on the LED indicators, and the auto power-off feature is a nice touch for saving battery life. I was able to test multiple Cat5e and Cat6 cables without any trouble, and it accurately verified the connections each time. The compact size also makes it easy to carry around, which is perfect for on-the-go testing. Overall, the Klein Tools VDV526-100 is reliable, efficient, and extremely user-friendly. It’s an excellent tool for both network professionals and home users. I highly recommend it for anyone needing a dependable cable tester!

This is a great little tool that has helped me to get my house wiring completed. It's not the most intricate but for the price it is a great little tool.

I like a good fixed function simple tool that doesn't overcomplicate things. This tool is pretty good, but it basically just gives you pass/fail , it doesn't tell you anything about what is wrong. Perhaps the worst example of this is if you mix T568A and T568B it just tells you "miswire" , the same generic failure as all other miswirings. Some other ethernet testers will tell you cross over or even tell you exactly which wires are not correct.

Works great helped fixing network cables for security system

Great little product !!!!!

I purchased this because I have a buried cable from the shed to the house for a camera that stopped working. Using this tester, I could see that my buried cable was no longer good. Using this tester, I didn't have to take other cameras down and move them around to see which ones worked and which ones didn't. Saves time and guesswork.

works GREAT!! Help me find and fix several bad crimps.

Great tester for quickly determining cabling issues. Received very quickly!
