Review on Efficient Power Saver: Electricity Saving Box for Home, Office, and Industrial Use - High Efficiency, US Plug, Energy Usage Monitor - 90V-250V, 30KW by Damon Mertz

I want to save money. I found this product interesting. As an electrical engineer, I understand the power factor correction that this device must offer. I took the opportunity and bought 5 pieces and placed them all over the house. My first impression when I received the devices was that they are very light. The inductors/capacitors in the device were very light. I was expecting something that would physically weigh more. The weight indicates an electrical component that can help with power factor correction. Rather than return the devices, I was optimistic and hoped the marketing was right. Since purchase I have received 3 utility bills with devices installed for the full billing period. In the first month my electric bill increased by 20% compared to the previous month and the same month a year ago. The next two bills were the same as the month before the devices were installed, up 6% and 27% compared to the same month last year. So after trying this product I had to follow my gut and not buy it or at least return it after receiving it. I have owned them for over 3 months and have no way of returning them. Save your money by not buying these devices.
