Oral-B iO™ Electric Toothbrush with a Smart Pressure Sensor

One of the brilliant new features of the Oral-B iO™ electric toothbrush is the Smart Pressure Sensor.
This sensor coaches you to apply optimal cleaning pressure by showing a red light when you’re pressing too hard, and a green light when you’re applying the optimal amount of pressure. This helps ensure you to get the most out of your cleaning experience.
