Try your Sync O, Sync 2, Sync or Chorus in their original shape first, and then use the two adjustable points to experiment with slightly different variations in shape.

Initial Use: Start with the original configuration of your Sync and Chorus to get a feel for their design.

Adjustments: Utilize the adjustable points to explore different shapes for a more tailored fit.

Exploration: Especially if it's your first time using a C-shaped vibrator, take the time to experiment on your own. Continue adjusting until you find a shape that is both comfortable and stays securely in place.

Enjoy the process of discovering the best configuration that enhances your experience and comfort.
