excellent product, efficient, enduring and robust. like all children, brushing is not necessarily the best time of the day; since it became a fun time and now we are being forced to ask them to stop brushing !!! To avoid having to change batteries often, I have inserted two rechargeable R06 high power (2700 mAh), which gives autonomy quite surprising on 6 to 7 months of use with a load! A must have!
