Oral-B's SmartSeries, not just a toothbrush, but a Bluetoothbrush (pictures)
The Oral-B SmartSeries electric toothbrush cleans your teeth and connects to your phone via Bluetooth for loads of stats. CNET takes a closer look.
The toothbrush portion of the SmartSeries doesn't look too different from Oral-B's previous toothbrushes. There's still the rechargeable base for which you can add the changeable toothbrush heads. The difference here is that the SmartSeries talks to your smartphone via Bluetooth 4.0 and shows a load of stats on a mobile app.
