Great device, get yourself more barrel connectors.
Worked like a charm. After years of plugging in cables and checking there's a signal via powering up the device, this was a huge time saver. I finally labeled all of my connections (should have done that in the first place) and will share this with friends when they need it as well. Time is money and this saved me a lot of it. Easy to use and the only thing that would improve this is additional barrel connectors. If you tracing four "cables," you're going to need those to make these work. The other option is to add the connector at the wall plate, but most of those were behind the TV or stand. Way easier to test the cable where it enters the box or TV.

Simple and Useful
This is relatively inexpensive for how well it works. I have cables running through my foundation, into a crawlspace and coming out all over the house. This let me identify what jack inside corresponded to which cable on the splitters outside and verify that the cable was good. Definitely worth the cost.

Time saver worth the money!
Works just as described. I was able to find the correct wire that went to each room in no time at all. The extra test caps helped a lot and we're worth paying a little bit more. The readout is easy to understand. The tester fits right inside my toolbox.

Works well.
I used this to test several coaxial drops in a four bedroom house. It worked well. The only problem I had was that one of the remotes broke. They aren't very sturdy so you have to be careful when twisting them on to coaxial endpoint. Other than that I am very happy with the quality of this device.

Brilliant little tool
I love how this device helped me map all the coax cables through my house. We don’t want extra things hooked up so we used this device to determine what’s what so we could label everything and really only connect the absolutely necessary things.

A great help
My attic had a jumble of coax that had no labeling and this thing was a great help with tracking each run down so I could document and label them properly. Worked like a champ.

Works Great
This tool made it easy to find both ends of my camping trailer TV wires. It’s so easy to use!

Well made and a great time saver
Why did you pick this product vs others?: I'm glad I spent a few extra dollars on this Klein; it's well-made, and the clips for the testers are good. I'm also pleased that I got four conductors. It made a tedious job so simple. I installed the different color connectors to trace different rooms in a new house. Then, I went up into the attic, and in a few seconds, I had everything sorted out. Without this tool, it would have taken hours to move the modem and see if it would start. It took me a few brain moments to realize that I should put the colored test units in the rooms and then go to the splitter with the device. Even if I never used it again, it saved my sanity on this one job.

I knew I was going to put in a physical line to an AP/Router I was placing in our basement. Could run ethernet ... but wait there is coax in 2 different places in the converted apartment --- let's use MOCA. Was able to trace the three lines using thsi device, found 2 to be active and easily traceable to a central hub of coax and was easily able to trace from it to where I wanted it in the basement (also an existing line). Life was good - 2 existing lines connected together and I had a coax backbone. The device it self was easy to use and accurate, and I have it for when I need to trace where all the other lines go from the hub.

Un buen comprobador y manejable pero el mio vino defectuoso: los conectores azul y verde me los detectaba como azules los 2 el resto correctos. Solicité el cambio de articulo y sin problemas en 2 dias tendré uno en teoría sin fallos. #recibido el reemplazo del artículo, funcionamiento correcto.

Works as designed so far for the uses I have tested with. Knocks out four rooms without having to go up and down multiple floors in the house.
