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

I use a year. Bought for myself and my wife. At first there were very unusual sensations, but then I got used to it and now an ordinary brush is perceived as an anachronism. Cleans very well. It seems that the teeth have become a little whiter. Every 30 seconds, the brush vibrates, which allows you to move on to the next sector of the teeth. I find it convenient. The charge holds an average of one and a half weeks. It takes a long time to charge - 12 hours. But, in principle, if you put it in the morning after washing, then you can take it off before going to bed. All in all, I highly recommend this brush.
