No, it isn’t informative if you’ve ever read the manual to your dishwasher. Dude bought a car then a house and goes around explaining things about them that are clearly explained in owners manuals. He does some interesting videos like the pinball machine or jukebox tear down, but the rest mostly non-substantial filler. Dude needs to stick to electromechanical tear downs.
Get a grip, calm down, and do a little bit of research before spouting off. Histrionics don’t really serve anybody.
