No, power saver doesn't save power and this is why

Have you ever bought one of those plug in power saver that claimed to able to save power from your total household power consumption? Does it work? The truth is, it doesn't work.
In the video above, a YouTuber, GreatScott! explained why it doesn't work. It's all related to reactive power and distorted reactive power. Plus he is from Germany and many of these devices claimed it was a German technology. That really gives him a motivation to make this video and tell the audience it's bullshit and tear the product manual into pieces.
