Review: Todo perfecto - Todo Ok Review: My honest professional review as an IT tech in the work environment - 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. ## Features - 🌹【10-in-1 Multifunctional Network Tester】NF-859GT 10 IN 1: Cable testing, Optical Power Meter, NCV, VFL, POE Power Detection; supports RJ11/RJ45 (CAT5e/CAT6/CAT6a) network cable and telephone line continuity testing, POE testing (including supply voltage and polarity detection), port blinking location identification, and network cable length measurement - 🎁【7-Wavelength Optical Power Meter】Directly covers 7 common wavelengths.

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. ## Frequently Bought Together - NOYAFA NF-859GT Network Cable Tester with Optical Power Meter 10mw VFL,for RJ45 RJ11 CAT5 CAT6 POE/Phone Lines CAT3, LAN Tone Probe Kit NCV&Ethernet Wire Tracer Fiber Tester Network Tools - ZOERAX 100-Pack RJ45 Cat6 Pass Through Connector Shielded RJ45 Modular Plugs for Solid or Stranded FTP/STP Ethernet Cable - Klein Tools VDV226-110 Ratcheting Modular Data Cable Crimper / Wire Stripper / Wire Cutter for RJ11/RJ12 Standard, RJ45 Pass-Thru Connectors --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/629117663-ethernet-cable-tester-network-cable-tester-with-optical-power-meter](https://www.desertcart.fr/products/629117663-ethernet-cable-tester-network-cable-tester-with-optical-power-meter) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-09*
