    We have used the Phillips Sonicare line for many years. This is by far the best looking design to keep on the counter.

    Taking some time to get used to the vibrations. It is too much on the recommended 3 so I have it set to 1.

    This purchase has been a huge disappointment. I have had several electric toothbrushes and used them for years but this one started acting up several months after my purchase (3-4 months) and now (9 months) it stopped working altogether.
