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.

Be sure to read the instruction manual. Purchased this to trace a circuit....and it worked flawlessly. Highly recommend.

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

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.
