NOYAFA NF-859GK Network Cable Tester with IP Tester 10mw Visual Fault Locator,PING/POE/RJ45 RJ11 CAT5 CAT6 Cable Toner Ethernet Tester for Phone Lines CAT3, Ethernet,Wire Tracer LAN Network Tool

Todo Ok

At first, things were a little confusing as the menu system on the cable tester does not perfectly align with the instructions in the manual. Note that for the NF-859GT (what I am reviewing) is the last tester in the manual on page 28.Things I tested with their corresponding results:1. "user alignment" test AKAs "cont" on the menu. This will test that your cable is built properly. You can test it locally (on either device) or test it between devices for runs in your home/business. This function seem to work fine.2. "Scan" test AKA "wire detection" is the test used to find the other end of a cable. You plug the network cable into the "SCAN" port on the main device and then you use the probe device to find the other end of the cable. It has 2 modes (digital and analog). Both worked as expected.3. "Flash" test aka "port blinking" in the manual. This test will cause the port in your switch to blink. It worked just fine on my switch (see picture)4. "Length" aka "network line length test" in the manual. This is supposed to test the cable length. I tried it on a 15 foot CAT6 cable I have and it measured 17.5'. So not accurate at least in my testing.5. POE test - this checks the voltage coming out of a POE switch. It worked fine (see attached picture)6. "QC Test" aka crimping test in the manual - This tests your crimps. It works fine.7. OPM - I do not have optical so unable to test8. VFL - I do not have optical so unable to testThere are a few quirks as you can see but overall, I think it does what it says and worth consideration if you are in the market for this type of tester.

Toner works great, light meter needs to be set so it doesn't change settings.

Great tool for testing CAT5 or Ethernet cable in general. I am a network technician and installing network equipment is part of the job. This tool is very helpful for testing cable and making sure that it works before setting up the equipment. It just makes the job a lot easier than having to plug in and test each cable to make sure it is working.

Looks really nice but Doesn't work very wellI, recommend better NOYAFA

This is a lot of tester for the money. It is pretty simple to get going, a quick look through the manual confirmed I had it figured out. The replaced 3 other tools I carried that I paid WAY more money for.Overall, this purchase perfectly matches its description and I am extremely satisfied with the product. It definitely deserves a five-star rating and I would purchase again!

Anyone that installs network cabling needs this tool. It can troubleshoot and analyze almost anything you need about the cable run. My only complaint is that you have to use certain rj45 ports based on certain functions you want to test.

The brand new scanner/toner that comes with the tester won’t take a charge via its USB-C port. It’s garbage and unusable. Waste of my money.
