I, who dreamed one day to brush my teeth with an electric toothbrush! Today it's done and I am really satisfied! It is not given to everyone to be able to buy toothbrushes at this price, but I admit that it is a premium product. 3 brushes provided each have their function and I love their brushing. Just read the user manual and the rest follows by itself. There is a light that warns of brushing too hard on the teeth. Small stops 30 seconds warn that we should move to another part of the mouth. Brushing this must be done in 2 minutes. When these 2 minutes are achieved, we see more pronounced judgments of the toothbrush. I find it really convenient and well designed. Another thing that I really like: the fact that blue bristles brush fade when they need to be replaced. This is an important indicator. If you brush your teeth two times a day with the same brush, it will be replaced after 3 months. And the more the more: the result! After brushing with this power toothbrush, it seems that there is a film on our teeth. On the contrary! It was at that time that they are well scrubbed! And that is where we see the clear difference with our little manual toothbrush ... Brushing, cleanliness and sharpness have nothing to do. The buy is adopt for life.
