Purchased at the same time as the HX9332 brush teeth, I must admit that these brushes last long enough despite my long and regular brushing ... No need to calculate the days remaining before the change of these heads because when the blue groove becomes white, it's that it is time to make the replacement ... Passing the electric toothbrush, I have actually felt a cleanliness improvement ...
