Simple tester at reasonable price
Nice build quality. Very quick to test, gives a clear pass or fail… however it doesn’t give any real information about which line or where in a cable (distance) the fault occurs… however Klein does make devices that can do this at a premium. Sturdy and dependable to test cables prior to deployment though in the field.

Basic Expensive For The Quality
expensive for an extremely basic tester. limited to only certain ethernet cables. not recommended. this brand has reinforced the fact price doesn't necessitate quality.

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!

As a advanced DIY'er building a security camera network, this tool has allowed me to check all my Cat 6 runs and fly leads. The removable remote is nice and small and lightweight. I'm on the fence with the LED; I have a short and all I know it's a short on the cable but I don't know what wire is the issue unlike other tools that do show the status of each of the 8 wires. But the result is the same - I have to chase a 200 foot wire for a problem. Not a cheap tool but a good size for your toolbox and simple to use. I always say you get what you pay for and I'm happy with this gadget.
