1. Multi-Factor Scoring System
Each electric toothbrush is evaluated across five weighted categories:
- Cleaning Performance (30%): Motor vibration mechanics, bristle velocity, and plaque removal efficiency.
- Gum Comfort & Safety (20%): Pressure sensor accuracy, haptic alerts, and bristle end-rounding quality.
- Features & Usability (15%): Timers, display screens, grip ergonomics, and modes.
- Battery & Charging (15%): Real-world battery longevity measured over twice-daily 2-minute timed sessions.
- Value & Ownership Cost (20%): 2-year total cost including required replacement heads across UK retailers.
2. Sample Procurement
