4 pcs. (1x4) of brush heads to E-Cron® teeth. Replacement Oral B Precision Clean / Flexisoft (EB17-4). Fully compatible with electric toothbrushes Oral-B models: Vitality Precision Clean, Vitality Floss Action, Vitality Sensitive, Vitality Pro White, Vitality Precision Clean, Vitality White & Clean, Professional Care Triumph Advance Power, Trizone and Smart Series .
Very disappointed with this purchase, certe sold as a simple test brush supported when you brush your teeth lightly pressing the brush and then stops the rotation with the Oral B brushes rotation did not even stop pressing lightly.
