Oral-B iO Series 6: what it gives up
- Drops Super Sensitive, which the cheaper iO4 and iO5 have
- Oral-B does not describe how this model's pressure sensor signals
- No battery figure: of the iO range, Oral-B gives one only for the iO2
- One head in the box; the iO7 ships two
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
