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

I use the term "year." Purchased for both me and my wife to use. The first few times I used it, I experienced some pretty strange sensations, but after some time, I grew used to it, and now I find that a regular brush seems like an oddity. Very effective at cleaning. It would appear that a slight whitening has taken place in the teeth. The vibrating brush alerts you after thirty seconds to go on to the next section of your teeth, and it does so by pulsating. I find it convenient. On average, one and a half weeks' worth of charge is retained. It requires a significant amount of time to charge, specifically 12 hours. On the other hand, if you put it on after you wash your hair in the morning, in theory you should be able to remove it before retiring to bed. In conclusion, I cannot speak highly enough of this brush.
