Easy, correct, loved it

This works exactly as described. I was able to trace back 12 different coax feeds from the distribution splitter to each TV hook up -- and it took less than an hour! I also discovered a splitter buried in my attic that was the reason why my antenna signal was weak in just one room -- the splitter looked like a nail went through it. I have 12 TV hook ups and am only using three (do I really need 2 hook ups in the dining room and 4 in the living room????). I debated getting a distribution amplifier, but this was much less expensive and the distribution amplifier would have been overkill as I really only wanted to isolate the 3 hook ups I use. Even though I may not use this again for a while or often, the low cost made this worthwhile for me.

I moved into a house with cable everywhere and cable outlets everywhere thanks to several different satellite systems over the years. This device made it so easy and efficient to identify outlets and match it to the cable in the basement where they all end up. You can install all 4 plugs on 4 different outlets at the same time. Then go plug the device into different cables and if youve matched any of them, it will light up with the corresponding color of the plug you used. That means 4x less times going up and down the stairs!

Easy to use and saves tracing wires under the house.

Good product. Value for money. Easy to use

So couldnt get it to work when it arrived was going to just return it. However after testing the batteries that came with it surprisingly they were no good. Made trip to store bought 4 new watch batteries & it works as advertised. Nice being able to test for lines without going back and forth. So giving only 3 stars because should not have had to run to store to get batteries before being able to use.

It worked the first time I used it and then would not work when I tried to use it again.

Good tool

Not bad

I wish the folks who built my RV had used one of these tools. There was a connection that had fallen off of a tee inside a wall and the tool helped me to find and repair the flaw in the initial cabling. Now my aerial works just fine.
