## Overview

The iO is Oral-B's best technology: Clinically Proven 500% More Plaque Removal Along Gumline versus a manual toothbrush. The i04 coaches you to a perfect clean. This is real time personalized coaching. The accompanying App shows your daily brushing report. Having 4 Brush Modes (Daily Clean, Whiten, Sensitive, and Super Sensitive) Oral-B is on your team for your everyday brushing task. A Round head and gentle micro-vibrations, the Magnetic interaction delivers smooth, harmonious motion through a Synchronized cleaning action (micro-vibrations synced with oscillations). A Built-in-2-Minute Timer ensures an even easier experience, helping you get an optimal clean on all your teeth. The Oral-B's quadrant timer breaks the two minutes up into four 30-second intervals to clean each quadrant of you

## Why we picked it
