Klein Tools 80016 Circuit Breaker Finder Tool Kit with Accessories, GFCI Outlet Tester, 2-Piece Set, Includes Cat. No. ET310 and Cat. No. 69411

This is honestly a fantastic tool, and I couldn’t be more impressed with its performance. One of the standout moments for me was when I was trying to locate an unknown breaker in a breaker panel—something that can be a real hassle, especially if you don't have the right tools. This tool made the process so much quicker and easier. What would’ve been a guessing game or a time-consuming trial-and-error process turned into something almost effortless. Not only did it help me find the correct breaker without any headache, but it also made me look like I actually knew what I was doing—always a plus when you're trying to impress friends, family, or clients! I’ve only scratched the surface in terms of using all the tool’s functions, but even just using it for this one task, it paid for itself. Honestly, after that experience, I knew I’d gotten my money’s worth. The fact that it saved me so much time and frustration made it a solid investment right from the get-go. It’s one of those tools that you don’t realize how much you need until you use it—and then you wonder how you ever managed without it. While I’d highly recommend this tool to DIYers—especially if you’re someone who enjoys working on electrical projects or home repairs—it’s definitely versatile enough to be useful for professionals as well. Whether you’re just dabbling in home improvement or you’re a seasoned expert, this tool offers enough reliability and functionality to make it a handy addition to anyone’s toolbox. In short, if you’re on the fence about it, don’t be. Even if you just need it for a single task (like I did), you’ll quickly see that it’s worth the investment. Plus, it’ll definitely make you look a lot more competent than you might feel in the moment—always a nice bonus!

Klein hit the nail on the head with this product. Very affordable product for what it does. Light indicators check wiring accuracy, GFCI test works great. Find the breaker you need easily with one person. The kit comes with a light bulb socket adapter, alligator clips for bare wire, and a 2 prong adapter. Carrying case seems heavy duty and durable. Overall great product, easy to use, and quality built.

I picked this up primarily for projects around the house like replacing outlets and doing minor electrical work, and it has performed exactly as expected. The breaker finder makes it quick and easy to identify the correct circuit without the usual trial and error of flipping breakers back and forth. It consistently detected the right breaker during my testing, which saves a lot of time and frustration. One unexpected bonus was the included bulb socket to outlet adapter. I actually used it while traveling when a condo balcony didn’t have an accessible outlet, and it ended up being incredibly useful. That kind of versatility makes this kit more valuable than it might seem at first glance. Build quality is what I expect from Klein — solid, durable, and dependable. Klein has always been one of my go-to brands for electrical tools, and this kit reinforces that reputation. Everything feels well made and designed for real-world use rather than occasional DIY novelty. The tool is straightforward to operate with no learning curve, and it’s compact enough that I’ve added it to my everyday carry tool kit for home maintenance. Honestly, I don’t have any negatives to call out. If you do electrical work around the home even occasionally, this is one of those tools that quickly pays for itself in convenience.

The important consideration here is that you MUST run the device slowly over all your breakers so it "learns" them, do not pay attention to any beeps you hear while doing this first pass. This kit worked very well for me after moving to the new house; the breaker panel was not labeled as well as it could have been and this was a real time-saver, especially the light socket adapter. I found it to be accurate, easy to use, and would recommend it over other kits I have used in the past for mapping outlets.

I bought this item last year and finally was able to use it today when our ceiling fan stopped working. The Klein circuit breaker finder is AWESOME! it was so easy to use and most of all, saved me multiple trips going up and down the basement. I found the matching breaker immediately!!!!! What a time saver! This is a must have for all home owners!!!!

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.
