I've heard a lot of people bad mouth it, and even in my Karate class, I never used the stuff while sparring, even grappling, but I went to a seminar today and it was quite affective. It wasn't just intercepting an unbelievably slow punch, either, we did all sorts of stuff. One of the teachers there said he knocked out a kickboxer with three pressure points in succession and he was the best one there.
