Description

With the Oral-B iO 9N Black with Extra Brush Attachment, you can brush every tooth thoroughly. Thanks to 3D tracking with AI, you can see exactly how you brush in the app. This way, you'll get a detailed mouth map and won't skip any spots. You can choose from 7 brushing modes, like the sensitive brushing mode or a massage brushing mode. You'll always have the right mode for your mouth this way. The interactive display provides useful feedback. You can see which brushing mode you used and whether you brushed well, for example. With red, white, and green light, the toothbrush indicates whether you're brushing too hard, too soft, or just right.

Doesn't last long enough.

Ease of use
Polishing quality
Lifespan

Unfortunately just after the 2 year warranty it now only lasts 1 minute with a full battery. I see this in other reviews too, for such an expensive product you would expect a better lifespan

Cleans super

You brush much better
Clear app
More drooling

Great brushing, and the app lets you easily track where you're brushing. The dental hygienist noticed. It was strange, though, that it broke after two years. And my husband's broke two weeks later. It was as if it had a timer for when it would break.
