NOYAFA Network Cable Tester with Optical Power Meter, POE Test, RJ45/RJ11, CAT5/6/7, VFL, LAN Tone Probe Kit (NF-859GT)

Todo Ok

I rate it a 3 for a few reasons. 1 - the innovation and price for a value network tester, 2- a few functions work but not that accurate, the accessories included at least they tried. Honestly, I thought this would be an awesome tool for my networking needs but it short fall my expectations. Sadly so I had to return it. The tone generator part works but doesn’t work when the end of the cable is on a switch like Cisco or unifi. The cable length tester isn’t that accurate as it is close but missed a few feet or more. The manual covers a few models and it is not in details on how to use the function dedicated to my tester just highlights of the usage, there is no ip ping, the cable quality check works good, cannot detect hub or switch location via cable just to the end of the connected switch or router, even to that is a guessing game at times, love the display and the rechargeable battery but for professional use no. Would be nice to have it touch screen and an on board guide. Some more improvements needed to be done to the device and wish if they have a pc interface and firmware update as well. Would love to keep it if these functions work well. I only used it twice and had to let it go. We have a six month project to network a whole complex and this tool would be awesome if it works accurately. The fibre optic part is a hit and miss especially on long runs, wish they would improve on that and speed check plus to detect internet and coupler or where the cable is broken like how many feet away etc. that is my take on it. Hope the next gen model improves on this and I may consider it in the future.

After you get used to it, you can really troubleshoot with the scanner, use the built-in TDR, verify continuity, ping devices, etc. All in all a very very useful tool.

Toner does not work, and seller wont return my messages about a refund. This is the 2nd device I bought from Noyafa. The first one was a cheaper network tester. Found out it wouldn’t work half the time so I threw it away. Bought this one to see if its better as its a new product of theirs - nope, still garbage. Spend the money and buy a proper device from a reputable company even if it costs 3-4x times more.

My first use after getting this was to scan a network and see if it can list all the IP's. This was a disaster first try because the unit froze up, butons doing nothing, long pressing and combinations did not help, there was just no way to force restart, I did not read the manual so forgive me if I'm wrong. I had to open it up and disconnect the battery, after that it worked fine, I tried scanning the network about ten times after that and it work well, did not know what was up the first time? You also have to pay attention to set your IP up first, scan the network and assign one automatically, it seems to works fine, some other reviewer here has no success with this option so I don't know what's up with his unit. That being said all other functions work as they should and I did not encounter any other problems after that. The functions to select and change is counterintuitive and someone who has no experience with these things will take a while to learn. The thing is crazy light and feels like it has no guts, thought they forgot to put in the battery and circuit board! For the price you pay for all its functions that seem to work ok there's not much complaining from me. I went ahead and modified mine with a switch on the side to cut off power if ever it freezes on me again...
