Review on Electric toothbrush Oral-B Smart 4 4900, black/pink by Dana Dana ᠌

I use only one mode. By Bluetooth, I never connected to the phone as unnecessary. I like that every 30 seconds an intermediate timer is triggered. Different pros: It cleans perfectly (before when I used ordinary toothbrushes, plaque and pigmentation constantly accumulated, now my teeth are clean even without professional hygiene). Feels better than the base model. Holds a charge for a long time. Convenient stand for interchangeable nozzles and charging. Comfortable to hold in hand. Got cons: The discharge indicator works only when the battery is almost dead and the brush slows down. Useless thing.
