Brush teeth is not the favorite activity of my children. Each relief is therefore welcome. The D10.511 provides this through child-friendly form and color and the music at the end of the cleaning period. If you start to fidget after a few seconds, usually helps to point out that the music so now comes the same and they can not listen if you do not keep quiet * uff *. Altogether there are 16 different melodies. Variety is ensured. 5,600 revolutions (ie not too much damage to the sensitive children's teeth), a grip handpiece and extra soft bristles complete the picture of a perfect children's toothbrush. The device is suitable for children over 3 years. Conclusion: This toothbrush daily tooth brushing falls for the little ones just easier.
