Review on Electric toothbrush Oral-B Smart 4 4900, black/pink by Tawan Nuyok ᠌

I have been using the products of this company for more than 5 years, and I started with the most sophisticated brushes at that time, which then cost 10-12022 (although, due to the specifics of the work, they got it for nothing) But time takes its toll and both brushes, having worked for almost 5 years, died. Accordingly, there was a choice of new ones, having decided for myself that the functionality of the previous ones was redundant, and then such a gift, I took a try and did not regret it, everything is the same and the battery life is much longer.
