Review: Brinyte DIV05 (dive light)

True except I first read about the Aleto much earlier, here and here

What would you think would work well to seal the magnet?
I’d think the o-ring for spring would stand up to many cycles although I can see the click stops not being as smooth as a spring.

I’m interested in the DIV05 though and will probably try one or two, does it come apart at the bezel as well?
Am I correct that there is no switch, your simply unscrewing the head from the body enough to break the electrical path?
