    Plugged this in and the first month I saw a 10% reduction in our electric bill. It was the winter months and the most expensive time of the year. I purchased two and placed them near the Electric Box and another one further away at other end of the home. They seem to work. Waiting for Summer and the A/C time of year.

    I was told about this product from a family member whom praised this product. I since have ordered and utilized this product for my primary home and casita. My utility provider has an app where I can see the utilization of this unit has made a marked difference. Definitely recommend!

    We’ve had this for a few months and our electricity bill has gone down by at least $30 already! I’d recommend these. We have two in our house, thinking about getting one more.

    As soon as I plugged it into the outlet. I saw both lights come on. I really can’t say how much it will save me, until I get my next Electric bill next month. Then I can give a better answer. Thanks.

    This device has been plugged in for a full month and my bill which was consistently 260.00 a month even through the summer decreased to 132.00. My Electric consumption was actually cut in half. I came on here just to leave this review. I was not compensated in any way for this statement.

    Got this for my daughters their electric bill was over 200 each month after they started using this we waited until a full bill cycle to see if it works. And their will dropped 75.00 each month after. I plan on buy some for our house, once I get refrigerated air.
