Review: Reliable, Accurate, and Worth Having — Especially for Home Projects - 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.

## Questions & Answers

**Q: Will this tester work reliably on new circuits with afci, gfi or combo breakers? I dont see anything from Klein saying it wont but some had problems**
A: Mine turned red when held up to any of the AFCI breakers in my box, regardless of which socket I had the transmitter plugged into.

**Q: Wil this tool find other recepticals on the circuit?**
A: It will find everything on the circuit BUT you will have to plug the transmitter into each outlet or using the socket adapter included with the accessories kit into a light socket of a lamp.  It's really pretty easy process though and I didn't do what I just described in the previous sentence.  Once I found the breaker from the outlet I had plugged the transmitter into, I flipped the breaker off, checked to make sure the outlet was indeed dead, then checked each outlet or light switch in the room and that told me everything on that circuit breaker.  When I went to an outlet and plugged the transmitter in, and it lit up, then I knew I was on a different breaker, and then that began the process of finding the breaker for that outlet, etc.  I hope this makes sense.  Good luck.  It really is a great product and I had no issues at all.  The time consuming part was trudging up flights of stairs and to each room after turning a breaker off to make sure I got the right one.  But now every outlet and switch in the house is mapped to a breaker.

**Q: Why is this exact kit available at the same store for two different prices? One is $3 more than the other for the same ET310 and accessories kit**
A: I think stores do this in hopes someone will just pay more. Unless ther is something added, I would stick with the original item.

**Q: Will this work if the breaker is bad?**
A: Yes, it should because the wires are still connected even if breaker is bad
