Visor locks. Useful or not?

[Hitcher]

The XR-1000 visor lock is the little black thing jutting out under the edge of the visor just about next to your left eye.

It can either lock the visor down or keep if from shutting completely - thus allowing some more air to circulate.

I have figured out how to make it do that half-click thing -- one of the greatest features ever invented for a helmet. But I haven't figured out how to make it keep the visor locked shut.

Close your visor and twist it counter-clockwise.

It has three positions: Locked, neutral and slightly open.

Oh - and you can still force the visor open even when locked...

Close the visor then turn the lever the other way

They're such good visors you don't need it. Not to 220km/h anyway.

Nah, at least 280, well, so I have heard

My HJC CL-15 has a locking button on it. The little manual that came with the helmet said it was for improving the seal of the visor and reducing wind-noise. It doesn't.
Maybe once the pivot mechanism starts to wear out, the visor might not want to stay down at speed or something and then it would be useful.
