    It is a great toothbrush. Hook it up to your phone and it tells you that you are pushing too hard or moving too much.

    Works great, but I don't use the smart phone app. I would probably get the model without it if I were to buy again

    Every time I brush my teeth with this brush it feels like I’m at the dentist office. The vibration is intense at the highest setting. It’s an acquired feeling but leaves you no doubt that your teeth are clean. Well, that and the app that literally shows you the areas you missed.

    I love Sonicare brushes simply because they have helped me get into the habit of brushing for 2 minutes. I honestly don’t know the difference/feel the difference between the general “clean” and gym health function. This does come with multiple heads, a fantastic charging set up, and a nice travel case. I’ll have those beaut for a long time.
