I saw this device in handyman. the salesman claims that it can save the user 20-35% of electric consumption. this device works by plugging it to any outlet. one can use maximum of 2 devices per electric meter. any comment on this device?

    Curiously, how does it work? Has anybody elsewhere explained how? What is the technology that back up its claim - if there is?

    thanks, but do you know the technology behind?

    Yeah, how does it work? My thinking about these devices is that if these indeed work as advertised, don't these deprive appliances of their required wattage (or voltage -- not really sure)? And if appliances don't get the required power rating, wouldn't that cause them to break earlier than they should?
