I already had myself an electric toothbrush but had not acquired for my 12 year old son. I complained that it was not brushed his teeth effectively gold, since it uses its PowerUp, I see a real improvement. Indeed brushing time is determined by the brush itself and the teeth are rubbed correctly. Also brushing remains soft and does not cause bleeding in his gums. The use could not be simpler and time brush load remains reasonable unlike other models where several days are needed (I am not exaggerating!). Only default, there is only one brush in the box and I do not know if it is possible when purchasing next to differentiate which would allow the use of electrical support by several people.
