I'm very pleased with this device that probably saved me a few hundred dollars, and here is why.
This set includes a receiver to track an electrical line and a transmitter. The transmitter indicates if there is power from an outlet by lighting up.
I ordered this as a few outdoor sockets no longer had power, so I plugged in the transmitter and went to my electrical panels in my basement.
The transmitter sends a signal to the associated breaker even if it's off. I like how the receiver helps me find the line connected to the transmitter. By finding the line, I can double-check the breaker that it is on. Fortunately for this device, I could locate it as it was labeled a kitchen electrical when it was outside electrical.
After resetting the breaker, I checked the outside outlet, and it was working again. Before using this device, I turned all the breakers on and off, and it did not work, so I was ready to call an electrician. I ordered this device as a last resort, as a visit from an electrician with a fix would cost at least $200. This device helped locate the breaker box to test the breaker further and check the reset, saving me lots of money.
I highly recommend this product, and it exceeded my expectations. Well worth the price, and therefore, I rate this product five out of five stars.
