    Best feature and bang for the buck when it is on sale. Very good product and dentist recommended for gum care and preventing plaque build up.

    Just what I was looking for, love Sonicare. I have been using a Sonicare toothbrush since 2000. Feels like a dental cleaning after each use.

    This is my second Sonicare toothbrush. I purchased this one as a replacement after my last one started going out a little after 2 years. The app is super easy and really helpful to get the best brush in. The new feature that tells you if you're using too much pressure.

    Didn't think I'd splurge on myself through dental care but it was well worth it. The timed setting is a huge plus and really is standard for these smart brushes. The sonic vibration cleaning feature was honestly novel, and took me by surprise the first time I used it. It only took one more morning of brushing for that "break-in" period and I learned you don't need to apply a much pressure at all to get an effective clean. Be warned though for anyone who has not used a sonicare product before, the first time using it will not be the same as any other typical spinning or electric tooth brush! I have not used the app that comes with it yet but the various pre-sets have been more than handy for my dental needs.

    I did not know how much better I could learn to brush my teeth. The app teaches you how to correctly brush you teeth. I thought this was very expensive when my wife bought it but as I have learn to brush better it is defiantly worth it.

    After about 5 years, my old Sonicare batteries couldn't hold a charge. I wanted to try the newer version, and am satisfied. Although, I don't really need the extra options with this version. My dental hygienist, and dentist, have very little work to do since switching to Sonicare!

    Great toothbrush. Maybe unnecessary with Bluetooth and smart toothbrush heads. The app is really helpful. I have had a Sonicare years ago and have had other electric toothbrushes, and this one is by far superior.

    I like the sonic care toothbrushes and this is now my favorite. The app that guides you on cleaning teeth as you brush shows you were you are missing spots, doing too hard or too soft. My next dentist visit improved. Take the time to use the app, it’s worth it.

    So far so good I’m loving everything about this toothbrush. My teeth feel like I just left the dentist getting my teeth cleaned. All and all I’m extremely happy with my purchase and I think anyone looking for a new electric toothbrush these are definitely the way to go

    Love this one from Sonicare. It was well worth the investment. It comes with different types of brushes already, it cleans very very well. I know my dentist will approve.

    This toothbrush I great. The low profile heads for it make it easy to reach any corner of your mouth, much preferred over Oral-B. Charge holds for a couple of weeks! Took off a star because the carrying case doesn't recharge the toothbrush like the older generation model (at the time, same price) did. However the included glass cup also acts as a charger :)

    It's a very good toothbrush and delivers a very satisfying brushing experience, far superior to other Sonicare models. However it's very expensive and offers many unnecessary features. The app is incredibly useless and while auto program sensing brush heads seem like a keen idea, they aren't.
