Using the Satisfyer Pearl Diver is super easy. First, make sure the device is fully charged using the included magnetic USB charging cable. Then, turn it on and choose from 11 air - pulse wave intensities and 12 vibration programs according to your preference. You can switch between pressure wave and vibration settings easily. Place the attachment head, made of body - friendly silicone, around your clitoris for intense stimulation. Since it's waterproof (IPX7), you can even use it in the shower or bath. When you're done, turn it off and clean it with warm water and mild soap. Keep it in a dry place. Remember to charge it regularly to keep it ready for your next adventure. And always use it in a comfortable and private environment.
