Using the Screaming O Charged OWow Vibe Ring is a breeze. First, decide whether you want to place the ring around the base of the penis or around both the penis and testicles. Stretch the soft and stretchy ring to fit. Then, adjust the motor to your desired setting. You can wear it on top for a clitoral massage or under for extra pressure and vibration. When it's time to recharge, use the included USB cable. You'll get over 60 minutes of vibration time after a full charge. Since it's waterproof, you can use it in the bath or shower. Just make sure to dry it thoroughly after use. Keep it in a cool, dry place away from direct sunlight. This product is latex and phthalate free, so it's safe for your body. If you have any concerns, don't hesitate to reach out to customer service.
