SONNENGLAS Pro Power Save Stop Watt Energy Saving Device, Pro Power Saver Plug in, Energy Saver Device 6 Pack，Electricity Saving Box Use Between 90V-250V, (JN-1)

I monitored the usage in our home after installed all of them and found NO appreciable difference in my bill or consumption. Now I have no measuring device to see if it actually levels usage, but our utility sends a HOW YOUR DOING about half way thru the month so you can see usage whether you are about the same or more than normal usage. These devices made no difference that I could tell.

This product did not assist with lowering my electric costs, in fact it made the bill increase by $ 100.00 to be exact. 😡

Do not work don't waste your money. Purchased two Boxes of Anything my Bill went Up.

These are a total scam and do not work. They will actually increase your bill as they are nothing more than an inefficient green night light.
