This toy's for guys who are prepared to be in for a shock. Inserting the batteries and initial tuning are straight forward. As long as the shock or vibrator buttons are pushed the sensation is felt. Even on high shock output the shock is pleasantly painful when the ring is mounted around the balls but mounting the ring around the penis even close to the balls is really a punishing experience; you really know you're being punished for being naughty. This cock ring can be used as a solo or partner event. If used with a partner the period of shock application really needs to be agreed upon. For me it's been a good investment.
