Why we picked it
Oscillating-rotating brushes have the largest body of trial evidence in the Cochrane review of powered versus manual brushing, and the iO3 adds a pressure sensor that warns if you press too hard or too softly.
Best for
Most adults who want the best-studied brush style with a pressure sensor at a mid-range price
Not for
People who dislike the buzzy feel of a round oscillating head, or who want app tracking
The details that matter.
