| Feature | Why it matters |
|---|---|
| Needle Count | More needles (540-600) provide better coverage and less pain per needle. Fewer needles (200-300) may require more passes. |
| Handle Design | An ergonomic, non-slip handle reduces hand fatigue and improves control, especially for longer sessions. |
| Sterilization Case | A included case protects the roller from dust and bacteria, extending its life and maintaining hygiene. |
| Replaceable Heads | Rollers with replaceable needle heads are more hygienic and cost-effective in the long run, as only the head needs replacement. |
