Wasn't sure about the weight at first but the inner spheres rolling around give a subtle feedback that actually helps me know I'm engaging the right muscles. A few weeks in and my pelvic floor feels noticeably stronger during my workouts.

Wasn't sure about the internal rolling motion at first but it actually makes the whole thing feel more active than plain balls. The two-sphere setup is easy to insert and I can feel my pelvic floor working during my morning routine. Genuinely glad I tried these.

The double-ball design with the inner movement is what sold me, and it really does make the training feel more active than a single ball. I've been using them ten minutes a day for a few weeks and the pelvic floor difference is noticeable.
