It works as it's supposed to, and the sensitivity narrows after initial scanning. On my Cutler Hammer CH panels it works better if the front cover is off the panel, but it's apparently not so great across the breaker fronts themselves. I just bought it so there may be a learning curve for me, but other reviewers have noted the same thing with CH breakers. Also works for identifying wires on the same circuit in different boxes, not just the breakers themselves. With an old house and electrical many revisions over the years, conduit running everywhere, this is what I really needed. Surprise addition is that the transmitter that you plug in is also a receptacle polarity and ground tester and a GFI tester. I bought the model that came with the accessory pack that includes an adapter for Edison-base light bulb sockets, a 2-prong adapter for non-grounded receptacles (and needed with the light bulb adapter), and an adapter to connect the transmitter to wires, etc rather than plugging it into a receptacle. None of that is crucial, but it was a cheap add-on and wil be handy on occasion. I've had a cheap circuit identifier for years, the blue one sold under many names, but it's never worked well. The only thing that does reliably is turn on and beep whenever it's touched or jostled (no positive off switch). Not sure how many times it actually identified anythiing, except identifying me as a fool for buying it. And it wasn't really that much cheaper than this quality Klein tool. I've always been satisfied with every Klein tool I've ever bought, this one included. No doubt there are more exotic circuit tracers for specialty applications, but this works as advertised for simple 120 VAC wiring.

Works fine. Recommended!

I had 2 sets of outlets (dining room and kitchen) and 1 exterior light that I did not know the associated breaker. After reading reviews of this product (both positive and negative), I figured it was worth a shot. I followed the directions and first tried the accessory for finding the circuit belonging to a light fixture. The tool correctly identified the circuit after making the required 'learning pass' over all my breakers. I then tried the plug-in tool and it also correctly identified the circuit breakers for my dining room outlets and kitchen outlets. I have a CH panel, which some said causes issues with the tool, but it accurately located the breakers. Definitely recommend!

High-quality product that is easy to use. It's a great addition to any toolbox. Klein Tools are my go-to for all things electrical. I've purchased several tools from this manufacturer for myself and family members.
