    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!

    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.

    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.

    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.

    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).

    Bought this because my husband has one. So far it works good. The only problem is the cost. I think it is expensive compared to others, but it does make my teeth feel cleaner than other brushes I’ve used.
