    To be honest the toothbrush is amazing and I realized how neglectful I was using cheaper alternatives. The only thing I will say, is that the app is not something I use frequently and I probably only use 2-3 a weeks especially during a busy life, typically checking end of week summary. Overall though the quality of the toothbrush and how well it gets plaque, I'd recommend,

    Connected easily to the smart app, the app has a lot of useful information and guidance on how to brush, the pressure you are applying, the area that needs more brushing. The charging glass is a nice touch and the travel box is very useful.

    Good electric toothbrush, not great. Very loud. If it was quieter it would be perfect.

    I have wanted a sonicare tooth brush for quite a while, and finally broke down and spend the money! So far I am very pleased with it! I don’t think my teeth have ever been cleaner! If your on the fence, just buy it you won’t regret it!

    Great brush. It is quiet and does a good job. Hindsight, I didn't need all the bells and whistles, but it is a good brush.

    This is my very first electronic Toothbrush and I can tell there is a huge difference between this one and a manual obviously. You can feel it after brushing your teeth.

    This is best toothbrush ever. I owned a Philips years ago and it was great. Went to an Oral B, which was good, but not the same. Going back to the Philips is the truth. Great clean and mouth feel.

    Leaves your mouth feeling like you left the dentist. Recommend changing out heads more frequent than most probably do. Love the glass charging stand. Definitely class up from the standard toothbrush charger.
