UNI-T AC Circuit Breaker Tracer Finder Tool Kit GFCI Outlet Tester | UT25A Electrical Integrated Tester 90-120V Adjustable Sensitivity Beep Indicattion Alligator Banana Clip Adaptor

Works perfectly. Follow instructions of using low setting and turning it up until you get a beep. Plug in unit for socket tests wiring correctness. Nice price and value.

I bought a cabin which had a bunch of bad GFCI's and a few wiring problems. I used this to test them and to find the correct circuit breaker to turn off when I replaced the bad GFCI's and while repairing wiring. I have two breaker boxes, with the finder it was easy to locate the correct one. Finding the correct breaker was a little harder, you have to adjust the sensitivity lower until just one breaker causes it to beep. On max sensitivity multiple breakers will beep. Once I turned off the breaker, I verified that the outlet tester showed the power was off- the green LED's were off. The outlet tester is easy to use, just plug it in and the LED's tell you if it's wired correctly.

The transmitter seems really powerful as the signal can bleed into adjacent lines/breaker, even with the lowest sensitivity on the receiver. Overall, it works ok. Was able to locate the correct breaker. The plug tester is an added bonus.

Tools works like it should I had just bought the house and wanted to remove a plug that was on the floor Going from carpet to hardwood and didn't want to shut off all the breakers to do this It only took a minute or so to find the breaker that I needed

It’s a great product at a good price. Easy to use. Well worth the money

Although it's not as good as the more costly versions you see. It does it's job. The plug/outlet reader itself is worth the money. The sensor... tho a bit tricky to get the right sensitivity initially... is a great addition to a basic homeowner tool box. It is effective... once you get the hang of it. I'd recommend practicing on a known path/circuit breaker line so you are able to get the setup dialed in, before you trust it's information. I also found out was more accurate if you slowly scan the center side of the breaker line, as it has difficulty differentiating the true line source on the outer edge... especially if you have a box that is heavily wire. It was much more accurate on my new house, well sorted breaker boxes than it was build than on my parents older some what densely breaker box. NOTE* in any power situation always use patience, persistence and triple check for live/hot response either with a non contact line reader or voltmeter with the outlet or line you are dealing with!

The wiring in my house is crazy. One room in my house is supplied by three different circuit breakers and the only way I would have ever figured that out is using this tool. With this tool, I was able to simply & quickly identify every receptacle that is controlled by each breaker. Just plug-in the transmitter, & take the sensor probe to your circuit breaker box & touch it to the front of each breaker to instantly find the correct one, the one that beeps. It is very sensitive, so it might beep on more than one breaker, but whichever one beeps the strongest is the one that’s correct. It seems to be made of high-quality and strong materials, and gives you instant readings to determine which circuit breaker is connected to a given wall outlet or light socket.

The purpose for getting this device was so that I won’t have to flip all my circuit breaker switches off to find the right one. This did not work for me. I read the instructions, watched YouTube, read Amazon reviews for tips, adjusted sensitivity, the position and the distance of the toner - all of which did not help. It identified multiple, and the ones identified were not the right circuits! At one point, the toner made noise in two completely separate electrical panels while probing! (Mind blown!) I plugged in the transmitter to different receptacles, and in different rooms. Lastly, I took it to a friends house for him to try. He knows a lot about electricity and he did not spend as much time as I did with it before he determined that the device doesn’t work. We have conclude that this thing doesn’t work on U.S. homes built on or after year 2004. I was very hopeful and excited when I ordered the device - ended up disappointed.

Great product. Easy to use.

tool works well

Not sure if these really works. I was a bit confused. I got multiple readings.

Works Great.

Product certainly takes out the guess work when testing the outlets plug line back to the breaker.
