Well-engineered hardware is definitely interesting, but unfortunately this article is rather lackluster. I'm not even talking about the many typos, but absurd claims like the suggestion that the use of Torx screws "Protects Dyson from counterfeit" really should not make it into an article by somebody who claims that they are "engineers, like you".

Their try at explaining the physics involved also does not quite convey they feeling that they understood what is happening and how.
