My son has suddenly fun on brushing

The old simple toothbrush it was always a bit difficult, especially with my 4 year old son rich discussion. Actually, more for fun I looked for electric toothbrushes for children and came across again and again on the Oral-B.
Since my wife and I use electric toothbrushes of this brand and are completely satisfied, we opted for the purchase of electric children's toothbrush.
And lo and behold, suddenly, our son having fun on brushing, especially through the melodies played by specific time intervals, he makes really a joke of it to brush teeth certain regions between the melody periods. After the second tune, we may then also safe side again nachputzen all without discussion.
Price of the equipment and the replacement brush I find perfectly fine, and the battery has a very orderly life.
We are completely satisfied with the purchase.
