> 3 dayFinds 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

> 3 dayTwo 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.

> 3 dayFairly easy to use, plug in the transmitter in the test socket and move the detector over the breakers along a line down the breaker array on the side closest to the panel box wall and not near the panel center line . instructions say to turn the sensitivity all the way down eliminate cross-talk issue but I found a midpoint setting worked better. I would typically start at full sensitivity, sweep the panel to ensure it saw a signal, then step down the sensitivity until only one breaker trigger a response. Note I generally could not distinguish between the a/b breakers in a double gang setup. I did have one issue; the transmitter makes an assessment of the socket and can identify problems with the wiring. This worked initially, but after testing several sockets it consistently indicated an unconnected ground even on circuits it initially said were ok. I verified a good ground with multimeter so bad transmitter. I returned the unit and amazon promptly replaced it . havent had any issues since then.

Greater than one weekThis device gave incorrect readings from the outlet to the breaker box.

Greater than one weekI 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.

> 3 dayI wish I had one of these a long time ago. It works for me. As long as you understand you need to start out with the receiver on high sensitivity them gradually decrease it to lower sensitivity (go from general to specific to zero in one the exact breaker), you should be fine. The transmitter device seems to be exactly like one I already owned and are sold by themselves. It may just send some kind of signal the receiver detects. If you have an old home with multiple wiring revisions done over the years, this is a kit that will save you a lot of time.

> 3 dayIts only natural for the signal injected at the outlet to bleed over to other circuits. The receiver has to be able to filter the lesser signals and only beep on the strongest. This one does not. It signals on too many breakers to isolate the one I want. So, I took it out to my shed with 6 outlets and 3 breakers in the whole box. It signaled strongly on all 3 breakers. I moved it around and it still signaled on all 3. I spent quite a bit of time adjusting sensitivity to no avail. Im returning it and will hit the Home Depot a little later for a Klein. Oh, and the circuit tester shows open neutral on all breakers.

> 3 dayThe 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.

> 3 dayThis device is very easy to use and allowed me to determine a problem with the house wiring in the circuit breaker cabinet. I contacted an electrician and he was able to resolve the problem which could have resulted in damage to appliances and devices plugged into the affected outlets. I dont understand the whole issue but it had something to do with the neutral leads. The symptoms were this device sounded off on multiple breakers for widely separated outlets. The electrician was able to fix the issue fairly quickly and once he finished the device worked flawlessly.
