    This electric toothbrush is AMAZING! I have owned 2 previous electric brushes in the past and none can compare. The quality is second to none and my teeth feel amazingly clean after use. Thumbs up!

    It's a great electric toothbrush, but after I bought it I realized I really didn't want the bells and whistles of the "smart connected" features. It nags when heads get swapped on and off, I did not use any of the other smart features.

    Good product. I had the previous generation Sonicare brush but this has better functionality. A little expensive but delivers on quality.

    I was looking for a new electric toothbrush and picked this up at Christmas time. It works great and I really enjoy all the bells and whistles it comes with. The only complaint I have is that you need to charge it by putting it in like a glass, which is kind of unusual. Other than that, I'd highly recommend this product.

    Fantastic, my dentist actually asked what I use to brush my teeth. The dentist visit took like 5 minutes.

    I purchased this product as a Christmas gift for my wife, who loves technology. The fact that the toothbrush will send information to her i-phone sold me and she loves that feature.

    The charging case is great. I don't think I'll ever worry about a dead toothbrush on a trip but the price is very high and it basically does the same thing as the cheaper one(beyond connecting to the app, which i stopped after the first week).

    No, I would not recommend this to a friend

    I purchased the new Sonicare because it was time for an upgrade. This toothbrush is so far advanced and the app is very easy to sync up to and user friendly. Highly recommend!

    This is a powerhouse of a toothbrush! Not only can I feel much more powerful cleaning action than most other electric toothbrushes I have used in the past, it also has a quick pause in the cleaning vibration when it's time to move from one section of teeth cleaning to another. I liked it so well, my wife bought one, then after using it for a while, she bought the travel version to use when we take trips. We have used other brands of electric toothbrushes for years, but they all feel like they do a very weak job of cleaning when compared to the Phillips Sonicare.

    My dentist recommended that I start using a Sonicare toothpaste and I will never go back to using a manual toothpaste. My entire mouth feels unbelievable fresh and clean.
