Amazing tools for tracing wire or circuit breakers or understanding an outlet’s situation
Was able to fix our perimeter entrance gate and light that had no power. We traced the line to the house and found a hidden switch that was able to be turn them back on. Also when it comes to finding what breaker turns of what outlet or light this excelled where the simpler version fro Klein failed in our homes electrical setup. Now for the Outlet Analyzer it is super simple and works excellent giving you situational awareness. Highly recommend both.

Useless
This was completely useless for finding buried wiring. Also useless for identifying breakers.

Works well for trouble shooting
Moving into a house with questionable electric. Able to trace outlets back to the breaker box. Able to check outlets for improper wiring.
