This toothbrush is really top. I will not go into details which do not interest me personally whether it is a rotary motion trizone a "foam effect" or backlit fashion ... what matters is that this brush lets you clean and soft teeth, its usable time after full load is about 10 days and it alerts you if you rub too hard (large defects of many people in the words of my dentist) and therefore your gums are protected .
VERY good quality product.
