Review Image by Scott Gillett Scott Gillett
If you installed the units and your bill jumped the first month, don't freak out. After the first full month the units start leveling things out. Looking at my attached bill will confirm what I just stated. 5 months later I got a bright idea to add 4 more units. It screwed up my next bill. It went up about $60. The units work together to stabilize the flow of current and I disturbed the system. Long story short. Put the full number of units in that you want and leave them alone. Do not unplug. It will screw up the flow and your bill. I just bought 24 units for my church but have not gotten the first bill. The last one was over $10k. I will post again later with an update ... show more

    • Questioning its effectiveness.
Size: 2 Packs Color: STOPWATT
I bought 4 of them, however I have not seen any significant change in power, maybe $4-5 dollars less! I have followed all instructions and it has been 3 months in use since I bought them. I am skeptical about its effectiveness. I will continue on using to see if there would be a difference.

    • Seems to be reducing electricity consumption
Size: 2 Packs Color: STOPWATT
The device is based on a Tesla (the inventor) invention. Cannot recommend with engineering certainty but it looks like my electricity consumption has dropped, $20 in first month (during a very hot month, if so it has paid for itself).
