And I must say that I literally conquered by the progress I see here. For quite content price, there is an extremely effective toothbrush against dental plaque, which is (is?) One of my biggest worries. not to mention the TAS on the teeth (coffee / tea).
After one week of use we already feel the difference really, we see: significant reduction in plaque and, thanks to fashion white stains on the front teeth become lighter. In addition the clean feeling is felt on 1 brushing: the teeth are smooth, the food dislodged from between the teeth, brushing is really very effective! More bad breath for example.
We find brand youtube videos that explain how to properly use this brush: inclination relative to the teeth brushing time, the different modes etc.
Fully satisfied with my purchase especially as it is an investment in the long term ..
I will return post after several months of use to complete this review
