I am a regular of electric toothbrushes for fifteen years and since the daily gingivitis are a distant memory. The Oral B version provides a simple version without additional elements. Its price is affordable especially knowing the life of the base unit with Oral B (I gave my first oral B to my parents and it still works as well for 13 years). It works with the rotational movement of the brush along pulses and oscillations unlike the last born of the brand that offers a similar movement to that of a manual tooth brush. It provides clear and effective washing. Very good quality / price ratio.
