No space or time limitations thanks to its rechargeable batteries. Whisper mode. Body-friendly silicone. 11 programs. Waterproof for even more fun underwater. Pressure wave and contactless clitoral stimulation. Magnetic USB charging cable included. Lithium-ion battery. Press and hold the control button for 2 seconds to turn on the toy. The Satisfyer Pro Deluxe will then activate at the lowest massage level. Gently open your labia to expose your clitoris. Place the toy head over your clitoris, so that it sits inside the clitoral cavity. Once youve found the ideal position, you wont need to move the toy anymore. Tip: The experience is even more pleasurable with a water-based lubricant. Youll get more intense pulsations if you use the Satisfyer Pro Deluxe underwater (e.g., in the shower or bath). The vibration intensity is adjusted using the control button. Each press increases the intensity by one level. You can freely choose from 11 intensity levels. Once you reach level 11, you can reduce the power step by step by pressing the button. To turn off, press and hold the button again until the toy switches off. This toy is rechargeable, so it can be easily used wirelessly. Before using the toy for the first time, it must be fully charged. Use the supplied USB charging cable for this purpose. The two magnetic contacts on the cable must be attached to the metal contact points on the toy. If the charging cable does not attach automatically, plug it into a power outlet and wait a moment. The magnetic effect will reactivate, and the contacts will connect automatically. During the charging process, the LED indicator will blink. Once charging is complete, the LED indicator will light up steadily. The first charge may take up to eight hours
