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.
