I wouldn't normally write a review on a product like this until it has been tested in the real world; But since I don't know when the next power failure or overvoltage will occur, I did a simple test myself. Simple test: I plugged my fridge into Unity and into an outlet. As it says on the box, it didn't happen right away. There was a delay before the fridge turned on. I let it sit for a few seconds, then took it off and quickly put it back in (less than a second). Refrigmatic did exactly what was advertised. He sent groceries to the fridge only after some time. Additionally, line indicator status helps interested homeowners like me feel reassured that the home is properly connected and the device is protected.
