  • Very handy whether you're a home owner or renter.
Style: Circuit Breaker Finder
When I worked for a major West Coast city, the general services guys used Klein tools. Quite an endorsement. This unit is rugged and works well. It's most useful for trouble shooting circuit breakers that have been in the "on" position so long, the switch doesn't flip to the "off" position when it breaks the circuit. The panel LOOKS like everything's okay and you can't find out which one's bad. This tool quickly finds the bad actor. Highly recommended. ... show more

  • Awesome little tool.
Style: Circuit Breaker Finder
The l e d lights make it easy to read. It has great sensitivity to pinpoint accuracy. The quality of this device is excellent. Spokennoise and very portable, small enough size to fit in your pockets. It is very safe to use.

  • Easy to use.
Style: Circuit Breaker Finder
Mostly works as intended. Circuit tester works well. Sometimes trying to match breaker to circuit challenging. But that could be a wiring issue. Prevents a lot of leg work running from outlet to breaker box. Would buy again.

  • Great for tracking your breakers
Style: Circuit Breaker Finder
I encountered a problem with questionable breaker, so I purchased this tool. I tested it and found a couple of breakers had been mislabeled. I also found out that the breaker I had questions about (unfortuantely) is good while the line to 4 outlets is bad. I purchased another Klein tool that checks if a breaker is functioning okay, and it showed that the one I was concerned with was okay. This tool is worth having if you want to work on an electrical outlet on one side of your home and you need to find the associated breaker on the other side of the home, this is the tool for you. Unfortunately, it doesn't work with light switches. ... show more

  • Where has this been all my life?
Style: Circuit Breaker Finder
Our house was originally built in the 1930s and has breaker boxes in odd places. Very few of the breakers are labeled and it is a pain when one needs to cut power to a circuit. I saw someone on a video using this tool to figure it all out and had to have one. My wife made a drawing of the rooms in the house and noted the locations of outlets. After that we embarked on a labeling journey and this tool worked flawlessly. I've not used alight adapter to label those circuits yet. This is a really handy tool. You'll be the envy of the neighborhood ... show more

  • 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
