Quick answer: The Oral-B iO3 is a strong entry point into the iO family, combining the iO cleaning system with Sensitive, Daily Clean and Whiten modes plus visible pressure guidance.

Why it stands out

It focuses on the essentials rather than app-heavy features. The pressure sensor is useful for users who tend to brush too hard.
