good to use even for older children still

My two children (11 and 13 years) were electric during the last dental visit. Toothbrushes recommended.
Both children have a lot of baby teeth without any defect - neither to the milk teeth still in the permanent teeth. To maintain this, should the elec. Brush also especially for milk teeth (read: soft and small) have.
The dentist said this electric toothbrush from Oral-B Braun Advance Power Kids.
At first I had some concerns about being too childish designs - possibly comes, especially when a 13-year-old, not so good.
But since you do not have secure Mickey and Co, it was for my son (13) then ok.

Now I have read a lot about the music playing for some too low and too short. All I can say:
For us, the music is great.
Through music, the compliance with the minimum brushing time is made easier - no more. The music should really be only a short info. Longer and louder would rather disturbing for my two children and the brush would ship in the world toddlers.

Now, this brush can be used universally. We are very satisfied.
I also know now also brush Oral-B, which are kept and used neutral.
That's great and secures the whereabouts and use of the Braun Oral-B Advance Power Kids for the future.
