The pros:
Different types of brushes suitable
bleaching the hair to indicate when it is good to change the brush head
the main: the perfect clean feeling of time as expected with an electric brush
the weight of the brush and the pressure control.
Cons:
the battery can not be dissociated lithium will cause a release for ViaMichelin trash the product when the latter is HS
an excessively long loading times
hair too inflexible and too aggressive for my hypersensitive gums.
So I ironed my Sensitive Signal hyper soft bristles (although it also has its flaws) and gave this brush to my husband who has more resistant gums)
