Is this power-saving product really effective?

His electric meter is specially designed (reactive power creeping has been adjusted), and it has no effect on the normal and qualified electric meter. In fact, if you think about it, a street punk can break through the electricity meter, which is simply a joke that can win the Nobel Prize!

(The electromagnetic watt-hour meter has been used for more than 1 years. At present, there is no deviation in principle, not to mention a mistake, except that it has high power consumption and it is difficult to realize prepayment and remote meter reading by networking. The person who can really fix it can be said to have completely overturned the current electromagnetic theory and should win the Nobel Prize! )
