  • Breaker finder is fantastic! Circuit tester, mediocre.
Style: 3-Piece Kit
I was really wanting the breaker finder but opted for the kit because I wanted a dedicated circuit tester as a backup to my Gardner Bender wire strippers that have a built-in tester. The breaker finder works brilliantly! It is accurate and very easy to use. Absolutely love this tool. The circuit tester in mediocre, unfortunately. It seems to require direct contact with a wire to sense current. My old GB wire strippers can sense current from a couple of inches away and seems more reliable. If you want a breaker finder and already have a circuit tester, I'd suggest skipping the kit and buying just the breaker finder. ... show more

  • Worth every penny to ensure your safety!
Style: Circuit Breaker Finder
Worth every penny to ensure your safety. There may be cheaper products, and do you really want to put your personal safety in the hands of cheaper product just to save a few dollars? This is where a brand you can trust is most important. This finder works great and is very, very easy to use and paid for itself in just the very first use. ... show more

  • This is a very accurate product. The manufacturing quality is great.
Style: Circuit Breaker Finder
This unit works perfectly. I was able to identify the circuit breakers associated with multiple outlets throughout my house and garage. My neighbor has since borrowed it. He accomplished the same thing, and he is not usually very good at these types of things. Don't do like I did and first buy a cheap version of this tool just to send it back, because they just don't work reliably. Just spend the money on one of these and get the job done right with confidence. ... show more

  • Handy, but not as selective as I'd hoped
Style: Circuit Breaker Finder
Well designed, but the sniffer is not as selective as I'd hoped when trying to trace the breaker for a circuit. Seems subject to crosstalk from the wiring to the breaker, so it's difficult to identify the breaker without removing the panel cover. Perhaps two or more levels of signal power from the transmitter would help. The GFI test button is very handy. ... show more

  • Works great
Style: Circuit Breaker Finder
I used this nearly every day for two weeks to update/correct my CB panel labels. It does take a few minutes of practice to get the hang of scanning your CBs so that you get a reliable alert on the correct CB. I had to check 17 circuits, and I labeled every receptacle and switch with a CB number sticker (also purchased on Amazon). Well worth the money for me. Doing all this revealed and open ground circuit in my garage and I had an issue in my living room that I called an electrician to clean up/double check. I still have a mystery, double gang CB in my panel. It has been off since I bought the house, yet everything works. DIY recommendation, check every receptacle on your property (UPPER AND LOWER positions) with a three-light circuit tester. ... show more

  • Easy to use
Style: Circuit Breaker Finder
This was a gift for my fiance because he has learned to do all the electrical work in our house. This tool has made his life a lot easier for trying to figure out what breakers connect to what areas of the house because the electrical circuits are a mess!

  • A very useful tool
Style: Circuit Breaker Finder
I recently moved our kitchen from one part of the house to another room. This tool helped track wiring and identify and organize all the existing circuits, and create new ones where needed. It allowed me to allocate circuits to specific parts of the new kitchen more effectively. It's also helped me locate where all of the existing circuits' receptacles and fixtures are elsewhere in the house. I didn't build the house but have made many changes over the years - and the builder did not do things to code. With this tool, I could do the work myself, without help. ... show more
