Oral-B iO Series 9 Electric Toothbrush With 6 Brush Heads, Black Onyx

The Oral-B iO Series 10 Rechargeable Electric Toothbrush is a top-of-the-line option with seven smart modes that allow for personalized brushing, an interactive color display for real-time coaching, and 16 zones of brushing recognition. It comes in black and includes (2) Ultimate Clean and (2) Gentle Care Replacement Brush Heads and a charger. The charger can work for a 110-volt outlet and up to a 220-volt outlet. The toothbrush can fit in most toothbrush holders. The handle may not fit perfectly into the case, but it will still charge. While some customers loved the toothbrush, others experienced issues after several months of use. People reported that the battery would no longer hold a charge, the toothbrush would stop working after 30 seconds, and the bristles did not last long. Although the initial cost is high, some people found it to be a worthwhile investment.
