the days of simple toothbrush with manual operation are with us a long time ago. Since we bought the first electric toothbrush Braun certainly 10 years ago, we are stuck with it. Only the charging station and the power of evices has changed over the years.
This one I had to buy because my somewhat dated Oral B has slowly lost its battery life (about 5 years old).
Now everything is ok again. The fully charged toothbrush is enough for at least 1 week brushing teeth (2 times daily) and makes thus independent !!!
By the way, I advise of alternative cheap toothbrushes and other branded products from strongly - we have therefore NEVER been lucky
Good luck with one of the top items made by Braun
