Using the Pipedream Products Fetish Fantasy Shock Jock Therapy is a breeze. First, adjust the waistband of the jock strap to fit you comfortably using the snap buttons at the front. Then, connect the jock strap to the electro - power unit. To control the shock, turn the dial on the control unit. You can change the intensity from a soft tingle to a strong throb, and switch between 'SLOW' and 'FAST' for different frequencies. For a hand massage, switch the control unit to 'IN' mode and place your palm on it. When using the loops, switch to 'OUT' mode and plug them in. A key tip: always use the Shock Therapy Electro - Sex Gel when using this product. It helps with conductivity and stops irritation. After use, clean the jock strap and control unit with a mild soap and warm water. Keep them in a cool, dry place for the best results and a longer lifespan.
