    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!

    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.

    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've been using a Sonicare for years and it was time for a new one. The pressure sensor takes a bit to get used to, but overall I really like the toothbrush. You can easily travel for a couple weeks and not run the battery dead!

    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.

    our family switched from the round Oral-B toothbrush system to the Sonic care system and I was not disappointed. I believe that this system cleans your teeth while massaging your gums better than Oral-B resulting in great dental checkups.
