About electric toothbrush I had dreamed of since childhood)) In 25 years decided to ask her father frost)) My Santa Claus from those who will not search for cheaper and buy something that is high quality, not sparing of money. Esle honestly I didn't expect it to be so expensive ( in the range of 5T.) Well, the main thing that the dream has come true!
Now, with regards to a toothbrush: I charged it a day, and then I have enough brushes for a month ( this is if you use through the day, as I do) if you use it every day for 2 weeks enough.
Brush cleans teeth very well, and if you're in one place for long hold, she begins to pelikat (it seems that the enamel is not erased)
The effect is obvious, if you use it regularly, and it is better if dopolnitelnymi whitening toothpastes, for example, I use this here http://irecommend.ru/content/ochen-khorosho-otbeli... effect in 3 months.
