Using the We-Vibe Sync O Couples Vibrator is a breeze. First, make sure it's fully charged using the included USB cable. It takes about 90 minutes to charge and can run for 150 minutes. When you're ready to use it, place the outer arm against the clitoris and gently insert the inner O - shaped arm into the vagina. You can adjust the fit to your comfort. Control the intensity of the vibrations with the single - button control or use the included remote. If you're with a partner far away, explore the We - Vibe app for long - distance play. After use, clean the vibrator with mild soap and warm water. Make sure it's completely dry before storing it in the provided storage bag. Always use water - based lubricant for a better experience. Avoid using it with oil - based products as they can damage the silicone. And don't forget to check the user guide for more detailed information.
