Using your BMS Factory Rechargeable Bullet Vibe is super easy. First, make sure it's fully charged using the provided USB cord. Once charged, turn it on and explore the 9 different functions to find the vibration mode you like best. To clean it, use a mild soap and warm water. Gently wipe it down and let it dry completely before storing it in the matte storage case. Remember to keep it away from extreme temperatures and don't submerge it in water for too long. Also, always turn it off when not in use to save battery life. Enjoy your new bullet vibe!
