    I’m not sure about the savings part yet, but it does keep the circuit breaker from kicking off incessantly when 3 things ran at once. I’m sold, I’m buying another one for the other electrical branch of my house. It must be some sort of condenser that releases energy when a spike occurs. Plus it only takes one plug in away.

    Product is used with a window air conditioning unit. As soon as it was plugged in, the air conditioning unit seemed to run smoother and with more cool air. Electric bill is not due for another two weeks. We hope that this energy saver will help lower our bill.
