Review: Helped me confirm that it was indeed the cables i bought on desertcart that was causing disconnections - I was scratching my head wondering why even though the cable passed the continuity test why my internet kept dropping. I tested the cable connecting my ONT to my Router and confirmed there were breaks in the middle of the etherent line depending on how the cable flexed. I replaced the ethernet cable with a more robust one that came with my 10gbe network card and my internet has not dropped once since. It really was the cable the whole time. The length tester is hands down the most indispensible feature of this tester. It's more than half the price of a similar fluke tester but does the job plenty good for a hobbiest home networking guy like me. Continuity test is no longer enough, I'll be checking every cable i get from now on with this tester! The UI is super easy to use on the tester, easy to navigate. The backlight is perfect and the display has pretty good viewing angles for those moments you're contorted in the attic trying to check cables. USB C for recharging is also really great. The digital toning feature was kinda hard to use and felt useless vs the analog one which was much easier to use to identify cable runs. The only thing, and i won't deduct a star for this, the earbuds in the photo were not in my kit :(
Review: Good value, works well. - I've had good luck with this so far and I'm pleased with the very fair price. I consider the USB-C charging (for *both* Tx and Rx units) well worth the small upgrade cost from the next model down in their line. Mine did arrive with the receiver (Rx) unit turned on and its battery stone-cold dead. But once charged, everything works as advertised. The controls are simple and intuitive and the display backlight very helpful. In my experience, tools like this typically get used in poorly lit, overcrowded closets. I can't attest to the precision of the distance test, but I know it's reasonably close at my backbone length of around 75 ft (~23m). Even a +/- 5% is very useful for troubleshooting in my setting. One word of advice: They provide a USB-C cable but you're supplying your own charger. I was unable to charge using a 'smart' charger (e.g., Anker IQ). Apparently it only wants an older-style 5V supply. In general, this is something to be aware of with a many devices on the market. I made the mistake of recharging a dive computer with the included cable connected to my own 9V-capable Samsung charger and melted the plastic housing. Not every mfr. implements the necessary circuitry for the smart chargers to correctly detect and adjust. At least in this case, connecting an inappropriate charger PREVENTED charging which might have caused some damage. As such, this is not a con. Another thing to be aware of is that it's very easy to switch between tests and forget to move your cable. There are different RJ45 jacks for different functions. I'm embarrassed to admit how many times I did this. Slow learner, apparently.

## Features

- Cable Length Test: NF-8209S cable tester adopting the new generation chip and more accurate sensor technology, it can provide AC filter and analog signal and digital mode to track. It can measure cable length in the range of 1-500 meters and detect cable crossovers, short circuits and breaks.
- Scanning Modes: The Anti-interference line finder provide there scanning modes can be selected: normal mode/anti-interference mode/PoE mode, meet the work needs of different scenarios. Use it to accurately measure cable length without calibration.
- Port Flashing: This ethernet cable tester can through the flashing port indicator on the hub/switch, the hub flashes to locate the network port, which can quickly find the network cable on the switch/router. tcan be used for 10M / 100M/1000M hubs/switches.
- POE Test: Determine which pins are supplying power and detecting voltage, determine the type of PSE (according to/af standard), and detect the presence of AC voltage (50V-1000V). Test the physical state of STP and UTP lan cables.
- LED Light & Wire Pressing Function: NOYAFA MF-8209S network cable tester is equipped with an LED light, so you can use it in low-light or dark environments. It also add a wire crimping function to help you determine whether the crystal head is crimped well.

### ⭐⭐⭐⭐⭐ Works good
*by M***. on April 6, 2026*

Was wiring up a house with cat6. This thing did everything i tried, continuity, ringing the lines etc. For the money, it's good, but longevity is unknown. The only thing that seemed not perfect was ringing or finding lines as I had to try few times to make sure I had the right line but maybe it was just me using it for first time. Was thinking about getting the klinecs this but chose this for the feature that you can check if your crimp is good on single end. Don't think kline has that one but not sure
