Noyafa NF-810 Multifunctional Network Tester， Ethernet LAN Network Wire Tracker with Telephone Line Tester, Network line Scanning, Power Cable Scanning and POE Switch Test Functions

I had over 200 cables to identify. I bought this as a replacement to the one I already had, and it works great! I have an experience any false readings, and was able to identify all of the cables in a timely matter and get everything labeled correctly. I definitely recommend this product, not to mention it was a great price!

I have a lot of ethernet hubs and this item has been handy for tracing the multitude of cables running around the house.

These work pretty well. I've used them in a network closet that was mess and they identified the wire I was looking for no problem. I think these will work for most. Probably best for those who use a toner occasionally. Someone who uses them every day may want to spring for a better quality toner.

I needed a toner as I was tracing network cabling in my 2 story home. This tool is exactly what I needed to not only tone, but to test continuity on existing lines. I was able to install an open network rack in my closet above the door and pull lines down the wall like a pro, identifying each cable going to keystone jacks in our office using this tool. I’d highly recommend this!

Moved into a new home and I had no clue which wall ports connected where. This product is intuitive to use and very convenient. Worked right out the box and I mapped out the whole house in 10 minutes.

Good kit and a great value; but, the control knobs are not the best quality...they lack a definitive on/off position/click. Okay otherwise.

Es delicado instrumento sirve en teléfono y en electrónica trouble shutter. Quien lo sabe usar resuelve ahorra tiempo.

The pointer end of the tool is perfect for searching for a tone in the line.
