Oral-B iO Series 7: what it gives up
- Same five modes as the $160 iO6
- Screen is monochrome, where the iO8 and iO9 are color
- Oral-B says how long it takes to charge, not how long a charge lasts
- Its travel case doesn't charge; that takes the iO9, $110 more
- The iO8 adds a color screen, a sixth mode and a third head for $30 more
Oral-B iO Series 8: what it gives up
- Travel case doesn't charge; the iO9's charging case is most of its $80 premium
- Lacks the iO9's Tongue Clean mode
- Three hours to charge on the magnetic charger, per Oral-B, but no figure for how long it runs
