    Very good and a huge difference over prior brushes in the past. Charging is fast and the glass is an awesome touch.

    Great brushes. Function of toothbrush is great. App takes a while to get used to. Overall really like it but question it’s cost. Feel it should be a lot less expensive

    Good electric toothbrush that cleans my teeth very well. It removes a lot of stains. However it only runs for 2 minutes or 2 min 40 sec (depending on the brush head). If you want to brush your teeth for more than 2 minutes you need to turn on twice. Brush head is expensive too.

    It is a little expensive but works well so far. It does a great job brushing the back teeth since the head is thin to reach the back.

    I had not been paying enough attention to my teeth and it showed at my latest dentist appointment. I realized it was time to do something and after reviewing the options, settled on the Philips Sonicare - DiamondClean Smart 9700. Very pleased as it easily connects to an app, has a timer built into the brush so I know when to move to the next section of teeth, has a 14 day "ease into" period that lets you build up your tolerance to the brush pressure. The best thing for me is that the action of the brush counteracts the fact that my fingertips are numb (a factor in my previous neglect). The fact that I can just set it in the glass to charge is a bonus

    Toothbrushes do not need to be "smart" and the novelty wears off after the first use with the app.
