I used to be a cop. We tested these -- on ourselves -- and I'm talking the ones that were used in Cook County Jail (Chicago). They hurt. But that's it. If you are not afraid of it or if you are resistant to pain (i.e. intoxicated), these are crap. I've held one of these to my solar plexus for a decent 5-count, and yes, I was sober at the time. At least they don't claim anymore that these will knock you down and disrupt your nervous system for 15 minutes, which is what they used to say back in the late 80s.
Pepper spray is far more effective. Any device that relies on pain only is asking for trouble because it won't work on the people that are truly a danger. But Pepper spray is not only an irritant, it is an inflammatory. It will cause swelling of all mucous membranes and therefore constriction of openings. That means it will make it harder to breathe and harder to see (swelling of the iris) -- plus it hurts like hell and keeps on hurting (for about 30-45 minutes). If you don't believe me, google around some police discussion groups, or rent the first season of Jackass. Johnny Knoxville personally discovered just what I'm talking about. Pepper spray is by far the most effective non-lethal personal defense item available to the public.
