Material Quality | Sensitive skin, daily use | Medical-grade silicone (ISO 10993 certified) ▲ (Base) | Hypoallergenic, non-toxic, easy to clean. | Base: Less durable than Advanced. |
| | Reinforced silicone with antimicrobial coating (ASTM F2998) ▲▲ (Advanced) | Added antimicrobial properties for hygienic use. | Advanced: Slightly heavier, may require acclimation. |
Design & Ergonomics | Postpartum recovery, discreet use | Smooth, rounded shape with textured grip (Base) ▲ | Easy insertion/removal via attached handle; reduces slippage. | Textured grip may feel unfamiliar initially. |
| | Graduated weight distribution (Advanced) ▲▲ | Enhances muscle engagement for advanced users. | Requires gradual adaptation to avoid discomfort. |
Customization | Beginner to advanced pelvic floor rehab | 2-tier size progression (Base) ▲ | Scalable difficulty for progressive training. | Limited to basic size range compared to Advanced. |
| | 3-tier size progression + interchangeable weights (Advanced) ▲▲ | Full-body resistance customization for targeted muscle groups. | Higher cost; requires more storage space. |
Hygiene & Cleaning | High-frequency users, shared devices | Smooth surface for easy wiping (Base) ▲ | Resistant to mold/mildew in moist environments. | Requires manual cleaning; no dishwasher-safe option. |
| | UV-resistant silicone (ASTM D4329) ▲▲ (Advanced) | Can be sterilized via UV light for enhanced hygiene. | UV sterilization requires additional equipment. |
Safety Features | Elderly users, post-surgery recovery | Rounded edges with 0.5mm blunt tip (Base) ▲ | Minimizes tissue irritation during insertion. | Less effective for users requiring intense resistance. |
| | Dual-locking mechanism (Advanced) ▲▲ | Prevents accidental dislodging during high-intensity workouts. | Complex design may complicate initial setup. |
Packaging & Accessibility | Travel, gift-giving | Compact, sealed box with instructional pamphlet (Base) ▲ | Discreet and user-friendly for first-time users. | No reusable storage case included. |
| | Reusable silicone storage case + app integration (Advanced) ▲▲ | Tracks progress via paired app; protects devices during transport. | Requires smartphone compatibility; adds to product cost. |
Noise & Vibration Control | Home workouts, shared living spaces | Silent operation (≤40 dBA) ▲ (Base) | Ideal for quiet environments (e.g., apartments). | Limited tactile feedback for resistance levels. |
| | Dual-frequency vibration modes (Advanced) ▲▲ | Enhances muscle engagement with rhythmic stimulation. | Vibrations may disrupt focus during meditation-based workouts. |
