I get this newsletter sent to me every day and at the top, there's a random ad. Today's was for a device called the Powergard. The website says:
Save 10% and more on your monthly utility bill
or your money back!No installation required - just plug-n-save!
Often pays for itself in less than one year!
Increases motor and appliance life!
Reduces power surges!
UL, CE and RoHS tested and listed!
It also says it conserves the amount of power drawn from your local utility company "by storing otherwise lost electricity caused by inductive motors..."
What do you guys think? My first impression is to be skeptical.
