Oral-B iO3 Electric Toothbrush
Entry point to Oral-B's iO range: magnetic-drive cleaning, a colour-coded pressure ring, 2-minute timer and three modes, without app or display.
4.2 / 5
★★★★★ ★★★★★ Highly recommended
Strengths

- Drive iO magnetic drive with oscillating round head and micro-vibrating bristles
- Cleaning modes 3 - Daily Clean, Sensitive, Whitening
- Pressure sensor LightRing: white (too light), green (correct), red (too hard); motor slows on excess pressure
