Didn't expect the shape to make such a difference, but it actually fits comfortably and stays put. The central motor's vibrations are stronger than I figured for something this small, and things last noticeably longer.

Was a bit skeptical about the shape at first, but the vibration motor in the center is surprisingly strong and quiet. My partner actually laughed when she saw it, then stopped laughing.

Didn't expect the fit to feel this natural, but the ring stays put without pinching. The central motor's buzz is strong enough to notice right away, and it genuinely helps me last longer.
