The one shown is around $300. You have to pass a background check before they will sell one to you. The replaceable heads are in the $25 range. There is a lazer that you just point and shoot. The darts do not have to penetrate the clothing. The charge can be administered even through thick garments.

I've taken the 'lightning ride' myself without getting stuck with the probes. We used a training head with aligator clips and let me tell you, 5 seconds is a long ride.

I wouldn't no about CC purposes, but they are classified as non-lethal.
