So-called electricity saving devices like Watt, Miracle Watt, True Watt, Real Watt, Watt Rescue, Esaver Watt, Pro Power Save, Voltmod and other energy-saving devices like them do not work as advertised and Musk does not endorse them. These fake energy-saving devices are being sold to consumers falsely claiming they are endorsed by Elon Musk. Also, as soon as consumers discover these so-called devices don't work, it is going to be too late to return them. This is because the fake company selling the devices will shut down their businesses and create others under different names using the same fake devices.
