Now, every lead on our team uses one!"

"I’ve used the Fluke Networks LinkIQ Kit for my projects and it’s consistently accurate, reliable, and simple to operate. The kit includes everything needed, making troubleshooting effortless, whether you’re a professional or a DIYer. I highly recommend it to anyone needing dependable cable testing."

"This device makes network diagnostics straightforward and efficient. The clear display and user-friendly interface help me test both cable quality and network performance with confidence. Solid build quality and versatile accessories make it a highly reliable tool for any setup."

"I'm not an electrician by trade, but after struggling to figure out which outlet a stubborn light switch was connected to, I picked up this wire tracer. It made tracking down hidden circuits incredibly simple, and I even discovered and fixed a short to ground I wouldn't have found otherwise. Straightforward to use—just watched a couple of YouTube tutorials. Absolutely worth it compared to hiring an electrician!"

"This tool is excellent for tracing cables, especially Ethernet and phone lines. The tone generator is clear and easy to hear, even in noisy workspaces, and the build feels solid. It's become my go-to for quick troubleshooting and diagnostics."

"I had trouble finding a dead outlet in my house, but after some YouTube research, this toner and probe kit helped me identify the issue in minutes. Just be aware, the batteries it shipped with leaked, so I'd recommend using your own fresh ones. Once I swapped them out, the tool worked flawlessly!"

"I honestly didn't expect much from this tester at first, but it really surprised me. The dual mode wire tracer, accurate cable length measurement, and fiber testing functions work great. I put the fiber feature through its paces by intentionally damaging a cable, and it detected the change instantly. Battery life is decent and it charges quickly. While it's not on the level of a Fluke, it's accurate enough for nearly all of my daily IT tasks."

"This tool has saved me more than once when I'm out troubleshooting fiber in the field. The variable frequency laser and optical meter are incredibly useful for finding faults and checking light strength. I also like the Ethernet features—port flashing, QC, continuity, and length tests are all pretty accurate. Sometimes you have to use your own judgment with the readings, but that's part of the job. Given the price compared to name brands, it's a no-brainer for anyone working with both copper and fiber."

"I love having all my cable testing needs in one compact, rechargeable unit. No more juggling multiple devices—this tester covers everything I need.

"For me, the real standout is how simple and durable this tester feels—it's quick to get going, and the toning feature is by far the highlight. I also like that it comes with a case. The POE mode is super helpful, and the cable mapping gives me all the info I need on network runs. Wish it could do a bit more with RJ11/12 jacks without buying extra remotes, but overall, it's a solid tool for Ethernet and coax work."

"I found this kit to be a bit expensive, but it really helps reduce confusion when managing a lot of cables or trying to decode poorly labeled wires. It's the best value among name brands for this type of tool. I did run into a weird readout once, but it still signaled a problem and helped me fix it."

"After talking to support and using the tester, I discovered that it won't wiremap with my digital probe and has trouble when plugged into an active switch with digital tone. Despite assurances from tech support, it just didn't deliver as promised with those functions. If you need those features, you might want to look elsewhere."

"As someone who handles all the IT work for a non-profit, I can say this tool is a lifesaver for network troubleshooting. It gives me every testing and investigative feature I need and has helped me avoid the cost and hassle of outside help. For me, it's already paying for itself."
