    Absolutely worth the money. Not only it's elegant and handy, but the case will make it easy to take on trips, and the app allows you to see in detail your brushing tendencies and gives you advice on how to improve. Charger is also very nice, sleek and small. highly recommend it!

    The brush does the work for you! I love pairing it with the app to let me know where my problem areas are or it in brushing too hard.

    This is a great toothbrush that spared no expense. It's the first time I went electric so I wanted a brush with as many smart features so that I can see if I am brushing correctly. Within a month I got the technique down and I won't really be needing the extra smart features anymore, or even have a need to check them. So they are a bit pricey for that need, otherwise you can expect to receive the most amount of data with it. My next toothbrush will cost half this amount because I won't need the extra smart features.

    This is the third Sonicare we've bought and it is a very nice toothbrush. I will say that Philips has gotten very cheap with as much as this costs in that they no longer provide additional brush heads as with the other less expensive toothbrush systems. The last one I had only lasted 2 years. Thankful for Best Buy and the TTS protection though. Would recommend it. The charging case is very nice for travel and works well.

    If you are not using a philips sonicare or some sort you are doing yourself a disservice, i hated brushing my teeth growing up but with one of these the feeling is almost massage like and just part of relaxing in the shower for me now and my teeth feel as clean as if they had just been polished at the dentist.
