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

Worked just like advertised even came with a case and battery.

My house was built in the 1950s and added on to many times by people that didnt always know what they were doing. As a result, my wiring is a hodgepodge mess with outlets on different sides of the house sharing the same circuit in some cases. This unit worked on a few of my circuits, but most were not accurate at all (would signal on the wrong circuits). I have a mix of double and single pole breakers, all covered by a sheet metal panel. Playing with the sensitivity seemed to help, but it varied so much from circuit to circuit that I found it was faster to just start flipping breakers on and off while talking to my wife on a hand held radio rather than fiddling with the sensitivity setting each time. The unit seems well made, and is very easy to use. It would probably work much more effectively on a newer house with newer (and cleaner) wiring. But for my situation, it didnt work at all unfortunately.

Ease of use, identified circuit that the remote plug in transmitter was on in an outlet. Identifies active live circuits. Stores easily, inexpensive practical homeowners electrical aid.

Tried this in my office. Very difficult to calibrate. I could never narrow it down to just one circuit breaker.

Works as described

So this circuit breaker finder is not bad at all. I tried it a few times in different locations and for the most part it worked for me. Only one instance it didnt work as expected. Very easy to use, nice and compact and comes with a nice carrying case. Overall not a bad product at all.

Works like advertised and you get a nice case for storage

Works like a charm! Just gotta play with the sensitivity... start low.

I had this, and less than 1 year it failed to take proper reading of the outlet wiring. So the gfci part of that unit will prematurely fail but can still use it for circuit breaker sniffer. One of the LED bulbs will fail prematurely. So if you have a good outlet that you know and you plug this gfci plug in and only one light goes on, its a sure sign of this failure. So now, I just use it for circuit breaker sniffer, and a separate GFCI tester. Not happy.

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).
