recently there was this door to door salesman who tried to sell me a device that supposedly reduces my electricity bill, like a battery or something. he did a demonstration and it appears to work, according to his handheld meter.
i didn’t like him however, so i turned down his exclusive, one time offer and tried to look up the device on the net instead. turns out the product’s website looks iffy, and is in fact incomplete.
i’d like to know more about the product since my electricity bill is pretty high. what are the things called? do they work? is it some sort of scam?
