Interesting! I was wondering what in the world you could do with a computer inside a toothbrush. From the product page[1]:

- Zone reminder for uncleaned aread

- Intense pressure reminder

- Some kind of tracking through an app

- Send each other stickers through the display

Typical case of very niche/almost useful feature set for smart devices. If the zone tracking is accurate, it could potentially help a lot of people who have trouble concentrating on brushing. And some sort of reminder would be great I'm sure.

But bundling all that with an app and a big expensive display is just silly. An indicator LED and haptic feedback for over-bushed areas would be just as good (if not better) usability.
