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

Best money spent. This is by far the best tester I have for the low cost. Love the case that it comes with.

I 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.

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.

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

Its 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.

Could not adjust to work on any breakers, junk

This kit takes the guesswork out of testing electrical outlets, and it speeds up circuit breaker identification by narrowing the possibilities to a manageable number. I only wish that the receiver wand was equipped with a signal strength indicator, for better accuracy while finding breakers. The plug-in outlet tester/transmitter works well, with bright lights that are easy to see. A color-printed decoding chart is conveniently included on the label, making it simple to interpret the results. The test button works as it should, causing my bathroom/garage GFCI outlets to trip immediately. The tester is ETL Listed, giving confidence that the kit is safe to use. The circuit breaker finding/receiving wand gets the job done, but it’s imprecise in operation. The wand tells you (with beeping and a flashing light) when it detects a signal from the outlet tester, but it’s either alerting or not, with nothing in-between. That’s not ideal, as on my electrical panel, the wand alerts on up to five breakers simultaneously, and adjusting the sensitivity doesn’t help. Having some indication of signal strength might narrow that down to one or two breakers, but this unit offers no such help. Overall, this is a decent testing/locating kit, but the wand could be better at telling you what’s going on. As it is, the kit can locate breakers to within a handful of possibilities, and that’s certainly better than nothing, but I had hoped for a little more precision.

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.
