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

An excellent Oral B Smart brush that provides effective and gentle professional care at home. Medium-hard bristles cover the entire surface of the teeth and clean out food debris between them. The brush itself is conveniently located in the hand, does not vibrate much, due to rubberized inserts it does not slip when brushing your teeth. It works from a battery, I charge it at night, the charge lasts for a week for sure. The pressure sensor prevents the brush from injuring the gums and tooth enamel.
