    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

    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.

    Really aggressive cleaning if you choose the deep cleaning setting. Awesome travel and storage that comes with it. The app is an overkill though.

    I bought this brush after my hygienist recommended I purchase an electric toothbrush. After a week of using it, I went back for another appointment and the same hygienist asked if I had been using an electric toothbrush because my teeth looked so improved!

    This electronic toothbrush is like having a dentist in your mouth every night. Extra polishing and cleans in between the gums. Really helps with healthy teeth and gums.

    Overall performance is great. Brushing with the 9300 feels like a professional cleaning every time. The only downside is the app can get slightly bugged. The app sometimes registers the inside teeth as the outside, but the job still gets done.

    This toothbrush is amazing. I went out looking for a $100 max electric toothbrush. To my surprise this one was on sale for $89 (only the rose gold). At that point I decided this was the one to get and oh man. I’m truly enjoying this one. The brush itself is amazing and the phone app makes it even better. I’m about to change the brush for the first time so I’ve been enjoying it for a few months and I can honestly say I will recommend it.

    Never had an electric toothbrush. It does all the work for you, you just have to slowly move it along. Also hold a charge for a long time
