I like a Domme taking control of me in various ways, including my orgasms, so I like both of the things you described (as well as ordered edging) rather than just chastity as part of orgasm control play.

What I hate about it in my personal play is that the devices don't work on me and have an outsized effect on daily life (i.e., just trying to use the bathroom) when I do wear them on a limited basis. I have the personal discipline to not cheat because what is the point of the play if you do that, but some Dommes think it's a pointless exercise without being physically locked without a way to unlock yourself (even to just reset the device).

However, what makes me flinch with instant hatred is the way it is portrayed on the internet (mostly by fantasists and findumbs) as something central to any D/s relationship.
