The cleaning performance is good in. You just have to get used to, that the oscillations simply not feel like scrubbing with a manual toothbrush at the beginning. You can reach all parts of the mouth very well.
On the battery life you can not complain. We use the part now 3 months and have all 1 1/2 weeks recharge (we usually use only one of the devices in parallel rather rare).
The children brush is not bad. Our child likes the sonic toothbrush but not yet. He preferred the conventional manual toothbrush.
The handsets are good in the hand and are not too heavy. The size of the charger was another reason this type toothbrush to buy. It is not as big and easy to store in the mirror cabinet. Who has an outlet in this can charge the toothbrush right in the mirror cabinet, so that they not standing around in the bathroom.
A very small downside is that you the insertion holes (as it is called, that is the version for the handset) versüfft easily if you do not consistently after each cleaning the brush head cleans intensively. But this is certainly also with any other brush so, so I give no penalty.
