Hey guys I was wondering if anyone can fill me in on the whole PK ring thing. Of course i'm not asking anyone to expose anything. But rather give me some info/feedback/opinions on them. I have heard of them before but only lately after seeing PK versions of effects that I perform I was wondering if its worth the buy. And if at all possible if someone could explain to me what the heck an M5 system is that would be awesome. Cause i'm assuming that magicians aren't performing with guns now.
