    This toothbrush is fantastic if you want whiter teeth in 30 days. Ive never seen a toothbrush with so many options. If you value your smile get one

    So far I love this toothbrush. It does a great job. I mostly don’t use the app, because there really is no reason to do so.

    I have been a Sonicare user for years and finally treated myself to the DiamondClean Smart version, and I am thrilled. The varied speeds and pressures options meet all my various needs and I appreciate the light ring feature that detects if I am pressing too hard. My teeth feel incredibly clean after each use.

    This tooth brush doesn't pack all the features of the 9700 but it sure does get the job done! Comes with multiple heads for different mouth task.

    Breaks after 1 year. New one for free.

    So I’ve gotten this tooth brush 3 times. After I year the motor stopped so I called and they replaced it for free. Then after one more year, now 2023, it broke again so they are sending me another one for free. They have great customer service but I don’t think after 1 year it should break for a $180 toothbrush. However, I love this toothbrush and will never use anything else.

    The app feature is nice however I do not open my phone to view. The brush does "beep" when prompting to move onto next brush area.
