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.

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.

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.
