Opinions are like assholes. What makes a tech reviewer's opinion worthwhile is the facts they use to back it up.
A tech review video without facts is simply an advertisement. These fact-less videos would, hopefully, as evidenced by this controversy, alienate a viewerbase.
I do appreciate how you brought up "review guidelines." I'd never considered that a reviewer's statements might be very specifically constrained. I only saw one of these Dyson videos, Linus'. I noticed that he did not mention the price of the vacuum, like he would other products.
You didn't mention the price, either. It's $700.
One other thing no one pointed out is that Dyson is wireless-only now, which necessarily means obsolescence built-in.
I bought a Dyson animal (compact upright) nearly 10 years ago for $400. I've put it through hell and it has always been there for me. I would vouch for it in an instant. That said, I will probably have this vacuum cleaner for 10 more years, too. That hurts Dyson's bottom line-- is that why they are moving to cordless vacs?
I really, really would like to know if these videos came with "review guidelines" and if those guidelines waxed philosophically about being cordless as a distraction from their unavoidable death. Or worse, did Dyson demand avoiding price and negative discussion altogether?
