On a whim, which isn’t another steel hardtail btw :P, I purchased one of these….

Don’t, they are utter shite! The valve ‘interface’ is to ‘fancy’ and you loose air inflating/removing – thread engagement is not ‘clean’ and varies between each use even on the same valve. The rubber tube seems like a great idea to remove forces on valve but a) is too short, & b) is too short.
The ergonomics too are wrong, and the whole mechanism is beginning to feel worn/weak after approx. 10+ uses.
That’s all.
