Full review
Longer notes from the same comments we summarized above.
What people reported
Owners appreciate the deep cleaning the Oral-B iO Series 10 provides. Some users reported their teeth felt exceptionally clean, leading to reduced bleeding gums. The toothbrush is also noted for being quieter than a lot of other Oral-B models. A non-replaceable battery is estimated to last up to 10 years with proper care. With diligent cleaning after each use, some owners found the toothbrush remained "as good as new" and looked clean even after two years. The iO Sense charging stand provides visual feedback on brushing performance, which some found helpful.
Problems people mention
A recurring concern is the high price of the toothbrush. Owners encountered significant issues with the device's build quality and hygiene. Some reported a "horrible smell" or that the brush gets "disgusting so fast" even with daily head removal. A serious mechanical problem mentioned is the magnetic connector coming loose, which renders the toothbrush unusable with no apparent fix. Other durability concerns include the metal shaft snapping off if the toothbrush falls and general claims of poor quality compared to older models. The design may trap moisture in the motor gap. Some users found the app features "gimmicky" and preferred not to rely on a phone for brushing guidance. One owner's unit simply stopped working, while another noted the charging stand requires a constant power connection, which can be inconvenient in bathrooms without wall sockets.
Where owners disagree
There's some disagreement on the effort required for cleaning. Some owners emphasize rigorous daily rinsing and specific cleaning tools to maintain hygiene, claiming it prevents issues, while others find the brush gets dirty quickly despite efforts. There's also a question about the necessity of the smart features, with some finding the visual feedback helpful and others considering the app integration an unnecessary "gimmick."
Who it's for
The Oral-B iO Series 10 is for individuals who prioritize a superior cleaning experience and are willing to invest in advanced oral care technology. It may appeal to those who benefit from real-time brushing feedback and are diligent about proper device maintenance to mitigate potential hygiene and durability issues. Buyers should weigh the high cost against the reported cleaning benefits and consider the potential for serious mechanical failures.
