- How is the iO Series 2 different from the iO Series 3 and 4?
- The Series 2 is the base iO model: it has the pressure sensor and two-minute timer but fewer brushing modes and no display. The Series 3 and 4 add modes and, on the 4, a small display with coaching.
- Does it work with all Oral-B iO brush heads?
- Yes. It uses the iO-specific brush heads, which are not interchangeable with older Oral-B heads.
- How long does the battery last per charge?
- Oral-B rates the iO Series 2 for about a week of twice-daily two-minute brushing per charge. Heavy use or extra modes shorten that.
- Is it good for people with sensitive gums?
- The pressure sensor and gentle magnetic drive suit sensitive gums, but there is no dedicated sensitive mode on this model. A softer brush head helps.
- What is in the starter kit?
- The kit includes the handle, a charger and one brush head. Extra heads are sold separately.
- Is it worth it over a basic Oral-B brush?
- It is worth it if you want the quieter iO brushing feel and pressure feedback. A basic Oral-B costs less and still cleans well but feels rougher and louder.
