    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.

    So far so good. Getting used to the app and learning to maximize the use of the product. So far no complaints. My husbands hates the glass cup/charger combo. I think it could be different/better considering the amount it costs.

    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).

    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.

    The best toothbrush in the market! I get it, it's pricey, yes, but I promise you it's worth it. Had it over a year, came with two replacements, had to buy a couple already since it has to get replaced every so often. Works very well.

    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.

    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.
