Using the Calexotics Me2 Rumbler Strap On is super easy. First, make sure it's fully charged via the USB port. Once charged, turn it on using the simple controls. You can choose from 10 different vibration levels to suit your preference. When using it, pay attention to the G - spot feature for enhanced pleasure. As for maintenance, since it's waterproof, you can clean it with mild soap and water. After cleaning, dry it thoroughly with a soft cloth. Don't expose it to extreme temperatures or sharp objects. And remember to lock it using the travel lock before taking it on the go to avoid accidental activation.
