This ball stretcher has an immensely intense sensation for your male partner. What you're doing is placing your partner's scrotum into the rings, such that their testicles are under the bottom ring and the top ring rests at the base of the scrotum.
Then you start turning the screws; the first set of screws are for the rings to secure them around the scrotum. The next set screw (the large screw) begins to separate the two rings apart, and thereby stretching the scrotum. This stretch, combined with the built-in weight of the device will give your partner immense testicle pressure.
