What reviewers say
Reviewers agree it has excellent battery life and a quieter, gentle clean, and both found the simplified pressure sensor light hard to read. They differ on value: T3 thought it an effective, affordable upgrade from a manual brush, while Expert Reviews found the cleaning underpowered, the replacement heads expensive and the iO3 a better buy on sale.
