Must have
It's really cool to have a tool like this, it works very well and wont break your bank.

Not a bad household tool.
This isn't professional grade but seems to get the job done. I used it in several homes where installers poorly labeled the data and cable tv lines in a central communications box. Used it in some homes varying from 6 total cable/data lines to one that had over 40. Hasnt disappointed me yet.

PROS:
1. Its cheap. Units with similar capabilities cost about 3 or 4 times as much.
2. Has most of the bells and whistles. The pacakge comes in three pieces. There is a main unit that has only a phone and data connector (RJ11 and RJ45). The add-on unit that has a receptacle for the data connector to connect it to the main unit and offer capability for male coax or alligator clips (the inset picture in the product. The third piece is the sensor itself that looks like a long pen. It has a speaker with volume/sensitivity level control.
3. The sensitivity volume has a range of sensitivity that I haven't fully explored. I have bundled coax and data cables coming into a central hub. When I first tried to find a particular cable, I had the speaker turned up to loudest. This basically caused every cable to give off a signal. I then had to turn it down to isolate only the strongest signal from the cable I was looking for. If adjacent cables can pick up signal, this could be useful in certain situations.
4. It comes with a nice little case that holds and protects everything.

CONS:
1. The plastic packaging was poor (clear plastic shell packaging). The owner's manual had fallen out at somepoint in packaging/shipping process. I just today realized that the manual is available on Amazon's site.
2. Could be an isolated incident, but Amazon's normally speedy service got this to me in about 4 weeks. Very slow by their standards.

Very cheaply made
FYI, to all prospective buyers, this is a very cheaply made piece of equipment. I would strongly suggest going with a different model adn/or brand.
