Ouch.

I can see this device stopping rapes. But if you piss off a guy who's already willing to rape you by trapping his penis in a plastic condom using plastic spikes, what are the odds he's going to retaliate? Beat the woman? Kill the woman?

I'm still an advocate for self-defence. Punch him in the face with a set of keys sticking out between your fingers, kick him in the nuts, knee him in the face, and run. Or something to that effect.

Not to mention that the FAQ leads you to believe that the woman doesn't feel the 'condom'. What if she has consensual sex with someone, but forgets that the 'condom' is in there? Or heck, what if the guy who tries to rape her lays charges?

This device just causes more problems than it solves, IMO.
