Glad I picked this up
I use this whenever I’m adding or swapping outlets in the house and it makes finding the right breaker stupid easy, so I’m in and out of the panel in minutes instead of guessing.
Super handy tool
Used it the first night I got it to track down which breaker fed a random outlet in the garage, and it pointed me to the right switch in seconds while I had the lawnmower half taken apart.
