NOYAFA Network Cable Tester with 10mW Visual Fault Locator, RJ11 RJ45 Ethernet Cable Tester POE Tester Cable Toner, Rechargeable Anti-Interference Network Tester for Telephone LAN Coax Cable

This product will get the job done. I was also impressed this product came with a visual fault locator for fiber cable! Toning and probing with this device was also very good. The User Interface could have had some improvement. Cable length testing was not that accurate. I tried to test a 7 foot cable that was coming out to 300 feet... did not know what was up with that.Beware of the charging port breaking on you, which was what happened to me. Tried to plug this in to charge one day to find out that the mini USB port was broken. I only had the product for a few days....I would say this is a good tool, but for what its worth, a much better tool would be Klein's Tone & Probe Test and Trace Kit that is at the Home Depot for a cool $40. Much better experience with this, much better quality.

Very useful and so far incredibly accurate. In the first few days, I've used our tested most of the functions and can say this little kit is worth every cent.Reviews that state the length tester isn't accurate obviously can't read. It states it isn't for testing lengths less than 25 meters right in the instructions. Why do you need to test the length of a small patch cord anyway? I've tested it on Cat5e, Cat6, RJ59, RJ6 and even Cat7a. It helped me locate a cut RJ59 to within a foot instantly- something that would have taken me hours to trace out due to the location.The toner works great, although a volume control would be a nice addition.I haven't been able to use all the functions in the field yet, but I am confident this thing is going to be extremely useful. My only other complaint is the micro B charge port. It was a horrible design 15 years ago and just needs to go away.

Great Price, works well so far, not to great on shorter lengths of cable test lengths, real close in longer cables.I purchased the other 2 more expensive Noyafa units and had issues from them at the get go - one showed constant split pairs, and the other shows crossed cable no matter the cable condition, new or old - In a lot of tests. This unit is cheaper, has almost all the same functions as the pricer units by the same company, and it has outdone them, not sure why that's the case but it has truly. It packs enough functions to make it a must have at this price point. By the way, I love the Anti E Interference probe. Always hated that 60hz buzz the Fluke 3000 pro wand emitted, it's so annoying. This wand rejects interference from surrounding sources and focuses only on the transmitted signal. Would I recommend purchasing this unit, definitely yes !

In BNC test mode, does not test long cables over 10 m. Unintuitive operation. To test RJ45 it is better to purchase the simple devices for $10.

El dispositivo se miraba muy bien. Digamos que me trabajo bien 1 día, daba bien las pruebas de continuidad y los wiremap. Después de unos días, las pruebas de continuidad me marcaba errores en unos hilos, pero al verificarlos con otros comprobadores la continuidad estaba correcta, las distancias (con un cable de 25 metros) me lo marca a mas de 80 metros. Ya hice la calibración y sigue sin funcionar. Ya intenté restaurando y está igual.
