UNI-T AC Circuit Breaker Finder with Integrated GFCI Outlet Tester AC 90-120V USA Plug + Adjustable Sensitivity Beeper Indicattion+ Flashing LED Light

Be sure to read the instruction manual. Purchased this to trace a circuit....and it worked flawlessly. Highly recommend.

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.

Could not adjust to work on any breakers, junk

I ordered this to add to my electricians toolkit. Ive been to houses before to diagnose electrical problems. It can be frustrating when the circuit breakers arent marked inside the panel. So I thought this would come in quite handy. One of those tools you dont use often, but when you need it, it pays for itself. So I tried it out the other day. The outlet had no power. Using the tester, I was able to locate the circuit and it had a GFCI in the panel. I tried the transmitters GFCI test on a couple outlets in our house. The test worked perfectly. Next I tried the receiver paired with the transmitter to locate a breaker in the panel. The first try, I got nothing. I reread the instructions and then double checked the battery. I included a picture of the battery as shipped. I first glanced at it and thought all was good. The battery is shipped wrapped, inside the compartment, but its not connected. You will need to remove the battery, remove the wrapping and plug it in. After connecting the battery, the tester worked perfectly. I tried two outlets and was able to detect their breaker inside the panel. A great tool for identification purpose. The UNI-T transmitter is easy to read. The key is printed right on the tester for reference. I have a similar outlet tester with small LEDs on it. This UNI-T is much easier to see and read, glowing brightly. I tried it on multiple outlets, finding nothing wrong. The UNI-T AC circuit breaker tester and finder is a welcome addition to my toolkit. For the current price of $28, certainly a reasonable price for a tool sure to prove invaluable. Im happy with it and recommend it.

El producto es muy complicado y no es certero al usar e encontrar el breaker

This breaker finder is So easy to use our use it on so many things even on different floors and it detected with no problem

Got this to map out the electrical outlets for my new house when the electricians didnt bother to put the right info on the panel. This worked perfectly for every single outlet/circuit that I tried. This is really handy and Im really glad that I got it, even if I only need it for one use (if I labeled them all correctly). The only anomaly, there is an outlet that ZI feel is improperly installed, but when I plugged the receiver in to test the outlet, the two lights lit up green to say that the ground was fine. But when I plugged it in - the lights for the entire circuit shut down... Maybe the problem isnt with the ground, but I was sure that there was some problem that this should have detected. But I really love how simple and easy-to-use this is. It really is great. It even comes with a 9-volt battery, which I think is rare (in my experience).

Works like advertised and you get a nice case for storage

Easy to use

For sure not as accurate as the brand name tools but it gets the job done and just takes a little longer to figure it out. Totally fine for home use, Not for business use.
