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

Works like advertised and you get a nice case for storage

GFI shows open ground always, very poor breaker identifier. Waste of my money. I bought the Kline tester, works perfectly. Stay away from this unit.

Two functions in one product: Circuit breaker finder and GFCI tester. Fairly easy to use, but it does require some adjustments on the sensitivity using the adjusting knob on the scanner. Nine-volt battery is included, but not connected. Be careful when opening the battery cover as its tough to remove and will go flying if you are not tightly holding the cover and the rest of the scanner. Use gloves with a rubber grip for easier opening. A nice case with a zipper closure, but it could be improved with a label so one knows whats inside it. Since the case it black, its difficult to use a marker on it and the bumpy texture makes it hard for any white marker or adhesive-backed label to stick. Works well for plug-in / outlet circuits, but not for wall switches or screw-in outlets. Adapters for these sorts of outlets would be an excellent addition. Directions are well written but printed on very thin, flimsy, onion-skin paper. The paper is very easy to tear, and will be useless the first time it gets wet. I suggest taking an image of the directions, scanning them or both. Also, it would be nice if the vendor added a QR code on the scanner for use and care directions -- and used better quality paper. There is some sort of bar code on the scanner, but its not a QR code. Made in China. Reasonably well priced at about $28 at the time of our review.

I own lots of these, and I am always ringing out wires... if you read bad reviews, well, that will happen with these products... mainly because, they are very unique, tempermental, and each brand has its own personality. for the newb, it can seem like, its too hard to trace, but with some trial n errror, u learn what works. how? test on a circuit you know both ends... be sure to pick one in the middle of the breaker panel find a way to test, so it works, adj. sensitivity, distance, speed, etc. once you perfect one that works, u can then move on to the mystery circuits... overall, for the receptacle gfi tester, and the tracer, this is an amazing value, and it works! recommended! 4.5 stars

Finds breaker very well but says I have open ground and I got out my tester I know is good and it say they are fine. The tester part is inaccurate

I have several UNI-T instruments and I have found them to be well made and less expensive than bigger name brands. The circuit tester function of the device works well and is clear to read and understand thanks to the onboard labeling showing what the light combinations mean. The GFCI tester worked perfectly. The circuit breaker locator function takes a little more effort to learn to use effectively, but I quickly found a way to make it consistently locate the correct breaker. When I started using the locator probe I found that it would trigger prematurely if I touched the white part to the circuit breakers. Typically more than one circuit breaker would trigger the locator tone as I got close to the correct breaker and I couldnt adjust the sensitivity to prevent that (either there would be no detection or multiple detections). Remembering something I discovered with my underground wire tracer, I lifted the probe off the circuit breaker by about 1/4 to 1/2 and then scanned for the correct breaker. This resulted in perfectly reliable operation. That may be something specific to my brand of circuit breakers or the length of the wire runs in my home, but if you struggle with getting an accurate reading, give it a try and see if this is a helpful tip for you too.

I have a lot of double single pole breakers, So the unit triggers even on the half of the breaker that is a different separate circuit. However the audible tome will be louder for the correct half; and the feed wires, if sufficiently separated, will signal very discretely on only the correct circuit. So it works just fine. In fact works great.

I often thought something like this would be a godsend to a homeowner who does minor electrical repairs. Instead of turning on and off every breaker in the house, requiring multiple clock resets, you plug this into an outlet, go down stairs and Voila, you find the right breaker and turn it off. Of course you do the necessary verifications afterward, but this saves you a lot of running around (especially if you are alone). When I used this for the first few times, I was convinced it did not work. So I held off doing my review, convinced it was user error and having used this on multiple breakers since, figured out that was the case. If you have the sensitivity on low (spinning wheel adjustment you turn it on with), you will get no breakers showing as the right one. If you turn it on high, you will get multiple breakers. The secret is to turn this thing up or down till you get one. When you initially turn it on, it is on max by default, rotating down, it gets lower. I found this super confusing. The reverse would make more sense, or if the light got duller when low and brighter when high. I kept turning it the wrong way. But that is me. However I checked 6 outlets in my house and initially some showed multiple breakers until I adjusted the sensitivity down. Most often adjoining, but one was not. Even testing on one of those outlet extenders (ones that go over an outlet and add outlets, USBs and even a shelf), it got the breaker. For the most part, I have some breakers labeled, but like most houses; additions and changes to the structure make finding the proper breaker a bit of a hunt and peck operation. Not all are labeled. The part you plug in also functions separately to check for the status of the outlet. I know years ago at my Mom’s there was this one outlet that used to give me a shock each time I used it and I found out using one of these types of detectors that it was not properly wired. An electrician fixed that one. He was surprised that it was even noticed. Mine you, I got a shock every time I used it, so hard not to notice. Tools like this can help you make your house safer. One thing I nearly failed to mention is the nice carrying case this comes in. So often tools go in a bag or drawer and sit until you need them. This case holds everything including the instructions and to me is a great addition to keep the integrity of this set of tools.

Got my Item very fast and in good condition. I would buy this again.

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.
