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

50+year old building. Built on 3 times. 3 rental units. 5 breaker panels. This tool was a life saver for me.

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.

We have a home built in 1959. The breaker box has a few labels, but they mostly identify the 220 circuits for the stove top, oven, dryer and water heater. As for the rest of the circuits for lights and outlets, few of them are marked and Ive found a couple of them marked wrong. This works best with two people so you dont have to keep running back and forth. The sending unit is plugged into an outlet and the receiving unit is passed over the circuit breakers. When you have the active circuit, the receiving unit lets you know. Once you have gone through your whole house, there is never again that need to flip circuits on and off trying to find the right ones.

while nowhere near as good as the more expensive pro-level ones, this one works well enough to map out the mystery fuse box in the basement. Mine had just a couple labels- and even those were wrong. Now I can swap outlets and lights without having to take out the power on the whole house. The build quality is light and it wont take abuse like a pro tool- but its amazingly inexpensive and works.

This 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.

Needed to identify breakers that controlled outlets. Adjusting the sensitivity made the accuracy perfect. Very easy to use.

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

Skipped the breaker that I knew it was plugged into

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.
