Answer is right there at the top of the comments. Commenter: "Anyone else having a hard time finding peer-reviewed scholarly articles saying that this is a safe and effective method?" Video creator replied: "It’s simply a piece of exercise equipment and does not warrant medical studies like some type of a pharmaceutical drug" The answer is no. In all likelihood it does not work. Also the video thumbnail clearly uses different camera setups for the before/after, and the difference could be due entirely to perspective. Not to mention photoshop editing etc. As well as there being no scientific evidence, I also doubt if there's any proposed mechanism by which this would work. Without mechanism or evidence, it's 99% chance quackery.
