    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!

    Amazing cleanliness compared to Oral-B. That good teeth feeling like after going to the dentist every morning. Recommend over Oral-B.

    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

    It's a great toothbrush but I think one model down is just fine and saves a bundle.

    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.

    This toothbrush communicates with my phone and shows me the job I have done. Hint, right handed, the left side of my mouth was better taken care of than the right side. Who would have thought? It knows where I brush, how hard, how long. And shows me on the phone, coaches me … WOW

    Excellent toothbrush! It does everything that it is advertised to do. Electric toothbrushes have a tendency to be harsh on your gums. However, Philips Sonicare has a gum protection selection. Great buy! You will not be disappointed.
