Simply does not work.
Delivered quickly. The device works wonderfully. I am very pleased with the price as well
Living in a rural area, I experience outages several times a year. Having a device that monitors both low and high voltage and a time delay to prevent spikes is a comforting feeling. It is connected to a rather expensive hi-fi system of which some components were destroyed during an outage and subsequent voltage spikes.
Very easy to wire into the box.
I now have a switch rather then having to pull a string.
It is great!!!
Received with dead batteries
