Works well
I’m happy with my toothbrush. It does what it says, I brush 2 to 3 times daily and my teeth feel very clean and slowly whitening.

Love the four different settings.
I would recommend this toothbrush to anyone. I like how it beeps to let me know when to move to another location. I had thought with my regular old toothbrush that I was brushing long enough and now realize I wasn't. The Sonic care cleans very well. I really like the four different settings that determine how long you brush depending on what you are trying to achieve for example gum work, whitening etc.

I am not good at these kind of things but...this is the most amazing tooth brush I've ever used. My teeth feel like they have been polished after every time I brush.
