    Gets down good at the gum line but still think my teeth feel cleaner with manual brush.

    I purchased this as a replacement to an older pink Phillips Sonicare, that quit working. I love the quality, ease of operation and choice of color. You will not have regrets, if you make the purchase.

    Just buy the regular DiamondClean. The app and the glass cup are not worth the extra bucks.
