I think it works in this case because Zack has a high profile YouTube channel and a high degree of trust in his workmanship from that. As they say, regulations are written in blood, and I would trust an approved device over a chair from some no name company somewhere because I have more faith that it won’t break on me while I’m out and about. Zack is obviously an exception to that because of his reputation which I think will help him be successful in this endeavor.
