Surprisingly capable tester for Ethernet + fibre.
What I loved: Brilliant little toolkit for network work. The cable tester is accurate, quick, and easy to use — picks up wiring faults instantly. The wire tracer works exactly as it should, even in noisy cable environments, and the PoE detection is super handy when you’re trying to figure out which switch is secretly feeding power to what. The optical power meter is a great bonus for fibre checks — not pro-grade lab equipment, but more than good enough for field use and home labs. Build quality is solid, buttons feel responsive, and the display is clear and bright. What made me sigh loudly: Realising how many messy cables I’ve ignored for years because I didn’t have one of these sooner. Should you buy it? Yes — absolutely. Whether you’re doing home networking, small business installs, or homelab fibre/SFP setups, this little kit is genuinely useful and great value for what’s included. Accurate tests. Great tracer. Useful PoE and fibre tools. If this tester were a person, it’d be the IT mate who always turns up with the right tool and a spare cable, just in case. Would 100% recommend — perfect addition to any networking toolkit.

Great help and amazing value for money.
After reading the manual it is very easy to use. Great value for money and saves a lot of time with checking the connections. The cable length checking can help detect a damaged wire. The size is alright. The functionality is simple and the quality is good too. For more money you get stronger plastics but this is good and comes with a carry case too. It is fast to use.

Decent - maybe a bit pricey compared to similar tester
Initial impressions are good. QC mode is handy for checking your RJ45 connector isn't busted. Tested it on my home network, and the tracer worked well. The cable length detector in quite a nice feature. Maybe allow for a 10-20% variance either way but seems accurate enough to help you measure on a job with a bit more precision that just eyeballing and guessing internal cable runs. I saw some reviews saying it was useless but it seems fine on the cables I know the approx lengths of. Anything under 2.5mtrs won't register, and just make sure you have the correct cable type selected (my quality varies on product batches but mine seems alright) It's a bit annoying to no have indicator lights on the tracer, which double up for your continuity testing. Meaning you need to have the main unit in hand to confirm the cable your testing. As points get further from the cabinet, it's a chore walking back to confirm and then back again to change ports (as opposed to a simple visual on the passive end to help speed thing up)... So bring an apprentice with you 😅 Strangely doesn't seem to charge with Type-C to Type-C cables . Has to be Type-C to Type-A. Feels a but cheaper to hold than it looks and there are comparable testers for around £20 cheaper than offer similar functionality. Might be concerned if I dropped it a couple of times as I don't think it will hold up to massive amounts of abuse. Haven't had a chance to test optical cable. If this it's terrible I'll update the review but otherwise assuming it's serviceable. POE testing is a nice feature with real time information. Handy for quick confirmation. Port Flashing is a bit meh. It does a quick flash and then goes off for ages before flashing again. Would be nice if you could control speed and even the pattern. Honestly it's not bad for the price. It might be better place around the £50-60 mark but it's a decent tool for quick testing. If you're a DIYer and only using it a handful of times, it's probably overkill. But like that circular saw you've only used twice... When you needed it, you needed it. Professional or not, it's seems like a half decent tool to use before you need to break out you more serious equipment.

Noyafa Network Tester: Outstanding Performance for the Price
The Noyafa network testing tool is a genuinely impressive bit of kit, especially for the price. It delivers performance that punches well above its weight, standing up surprisingly well when compared to premium brands like Fluke … yet costing only a fraction of the money. In day-to-day use it feels solid and well put together, with a reassuring build quality that inspires confidence rather than feeling like a cheap alternative. Functionally, it does exactly what you need it to do, and does it reliably. Whether you’re tracing cables, checking continuity, or diagnosing basic network issues, it performs consistently and without fuss. The interface is straightforward to use, making it accessible for both seasoned technicians and those newer to network testing. The documentation isn’t perfect, there are a few minor grammatical slips, but it’s clear enough to follow and gets the job done. Overall, Noyafa has delivered a tool that offers outstanding value for money without cutting corners where it matters. Based on this experience, I’d be genuinely keen to explore more of Noyafa’s range in a professional setting. If the team are ever looking for real-world feedback or would be open to trialling products with a hands-on user, I’d be delighted to hear from them.

Great tester - bargain price
If you do any network cabling this tool is a great help. I use it almost every week when tracing out cables/points or terminating rj45 ends really useful for testing continuity and faults etc also does fibre too. Good size screen easy to use. Long battery life. Was a good buy. Very pleased

Great value for money
Great features for the price point. Of course there are better tools out there but nothing in this price range has the same feature set! There are reviews knocking it for missing features, and comparing it to Fluke and the like, but you must realise the enormous price difference. Pros: Easy to use Saves carrying multiple tools (VFL, network cable tester, toner) Feels like acceptable quality Battery life is good. Features all seem to work as expected. Length measurement is accurate give or take a couple of metres. Cons: It’s quite huge. Uses up a lot of space in a backpack! The receiver unit seems to turn on very easily. Multiple times I’ve got it out my bag and the receiver unit is on and gone flat. No alternative fibre connection options. The screw on adaptors are for SC, unscrewing these allows you to insert an ST, but an adaptor for LC would be a great addition.

It's ok
Gets the job done but do not expect accuracy or reliability out of this thing. The simpler and much cheaper model from the same brand works better actually (specially the wand) but lacks a couple of features namely the crimp quality test which I believe uses capacitive sensing to see if the pins are making contact with something conductive.
