> 3 dayAt first it was very good and useful, but within a week it stopped detecting the GFCI tester. Dont know what happened, item was taken care of and stored properly.

> 3 dayBought this tracer to make circuit location more efficient. We are now doing work for others and this tool is a necessity since you cant turn breakers on and off to isolate what is to be worked on. Here, the transmitter sends a signal that is picked up in the breaker box on the appropriate breaker. The homeowner is unaware of our effort to isolate the circuit. Excellent tool.

> 3 dayI just got off a call with a very helpful technician at Klein. I believe I learned the following: 1. To get this tool to have a chance of working, the technician told me that I should unplug ALL the devices I have plugged into any outlet in the entire house. 2. Even then, I should not expect that the tool will accuracy identify the controlling circuit breaker. In my case it identify 8 as the controller breaker. However, when I turn the 8th breaker off the outlet was still powered. Turning the 7th breaker off did remove power to the outlet.

> 3 dayThis thing is amazing! No more flipping breakers until I find the right one. I tested it on 3 known outlets and 2 unknown outlets. Worked every time, quickly, easily, and accurately. I can even tell which of a double-stuff (twin) breaker it is. Definitely follow the directions! I get the most accurate results if I relearn the label every time I move the transmitter, even if the tool has stayed on the whole time. Hit reset, learn the panel, find the breaker. Fast and easy. I got this as a gift. Definitely glad they got me the full set with the lamp socket adapter.
