Review on 🔌 Circuit Breaker Finder and Receptacle Tester for 120V Standard Electrical Outlet - Klein Tools ET300 by Mark Colbert

I chose this product because I have been using Klein tools for many years and I trust their quality. In about 20 attempts, after carefully reading and following the instructions, I haven't had a single successful chase. I started with a socket and switch combination in the same room as the switch box. I got a clear positive switch reading, turned it off and the light stayed on. I tested a known circuit to my saw that I installed myself so I know the correct breaker. I had no hits at all, like the right switch didn't exist. Tried the one I most wanted to identify and got a strong positive result. I turned off the breaker and the transmitter LED stayed on. Every time I tried this thing, I started over with the receiver off. I ended up using a brute force method to disable circuit breakers until I had the right one. This device has never existed before.
