Brand New in sealed box. The Oral-B iO Series 3 Electric Toothbrush features Oral-B's best technology, combining a dentist-inspired round brush head with micro-vibrating bristles for a professional purifying clean feel at home. This rechargeable toothbrush is clinically proven to remove 400% more plaque along the gumline*. The Built-in 2-Minute Timer breaks the two minutes up into four 30-second intervals to brush each quadrant of your mouth to help you get a complete clean on all your teeth. We watch the time, so you don't have to! Plus, the Pressure Sensor indicates optimal cleaning pressure and warns of too much pressure. The display panel lets you select brushing modes, alerts you when battery is low, and signals when it's time to replace your brush head.
