    Purchase for my wife and she loves it. It tracks your brush movement so you can easily adjust to ensure you are getting all teeth covers

    I love this toothbrush. I can now gloat whenever I go to the dentist since it tracks how you brush your teeth (how many times a day, how long, how hard, do you floss, etc). The app isn't as fancy as the one that comes with the oral-b brand, but it still does well.

    This is my second toothbrush I’ve bought of this model. Love it! Easy to replace the heads and Best Buy offers best price on the replacement heads. Recommend this. My first toothbrush lasted seven years before I had to replace it!

    This is simply the best Sonicare in the Philips lineup. This is a perfect example of the price tag justifying the incredibly quality upgrade one gets with this toothbrush from the other Sonicare options. (Although they are pretty good too.)

    Have always been a fan of Sonicare products. This is the best version yet. Swear by this unit. Can't be beat in my opinion. the features and technology are second to none. Fantastic brush system with many head options. Spend the extra money and get this unit. It will last you many years

    I bought this brush because my dentist told me i brush to hard and that effects your gum health. Been using this for a few weeks now and my teeth fell clean after each use and the moonier sensitivity i had in some gum areas is pretty much non existent. If you care about your oral health pick this up.
