Oral-B iO Series 4: what it gives up
- No screen; mode and timer feedback come from lights only
- Like every iO except the iO2, it has no published battery life
- The case doesn't charge; among iO handles only the $330 iO9's does
- At $100 it costs well over the iO3 for the case, app and one extra mode
Oral-B iO Series 5: what it gives up
- Oral-B's page contradicts itself on whether there is a screen
- Battery life goes unpublished, as on every iO above the iO2
- The iO6 adds a confirmed display for $40 more, which squeezes this model
