StopWatt Reviews - Is Stop Watt Energy Saver Legit or Scam? Cost

Below is the waveform of voltage and current of non-linear systems. Non linear systems include rectifier and switching converter. The shape of the voltage is intact but the current is very distorted which emphasizes a very low power factor. The first trial has worst power factor, so it has the highest current reading. The second trial registered an improved power factor thus the current decreases.
