App-Controlled Vibrating Kegel Ball Set
Choose vibration, weight-based resistance training, or both in your own routine.
Use Magic Motion App for vibration control and simple Kegel exercise support.
The weighted ball adds a traditional resistance option for pelvic-floor exercise.
Crystal Duo does not measure contractions or provide pressure-sensor feedback.
A vibrating trainer and a weighted ball in one set. Choose Crystal Duo when you want a playful, app-optional experience rather than a sensor-feedback trainer.
Use manual controls for vibration, or open Magic Motion App for app control and simple Kegel exercise support.
For pressure or multi-point feedback that helps you recognize a contraction, compare Kegel Coach, FitCute Rejuve, and Kegel Master Gen2.
Crystal Duo is not a sensor-feedback Kegel trainer. Use the vibrator manually or through Magic Motion App, and use the weighted ball when you want a more traditional resistance-style Kegel experience. For feedback-led guidance, compare the dedicated sensor trainers in the Kegel guide.

Use Magic Motion App for vibration control and simple Kegel exercise support. After the user with Crystal Duo connects it to their phone in the app, a partner in another city can remotely control it. Both users need the Magic Motion App and a stable internet connection. Crystal Duo does not use Magic Kegel App or pressure-sensor feedback.
