Many appreciate the long battery life, useful app, convenient travel case, and helpful pressure sensor.

    I previously had a Phillips Sonic and it was pretty good but this was an absolute 180 compared to the Philips, the interactiveness with the app is really intuitive.

    A smart toothbrush is a smart choice for a guided clean. It always leaves you feeling fresh like you just got a cleaning at the dentist.

    The best toothbrush

    Absolutely love this toothbrush! The feel of the brush makes your teeth feel extra clean. Love the different settings. The base doesnt take up as much room as the others. Only complaint is that it does not have a brush holder and the app doesn't allow for more than one peeson to connect to the base of the toothbrush.

    I highly recommend this toothbrush. First, I was doubting because of the price, but I am very satisfied after using it. It gives you real time feedback on how much pressure you put on your gums and you can monitor areas that you’re brushing on the app.

    Much quieter than my old OralB Triumph. The brush works well, but I miss having the flossing head from my old brush. I floss before brushing, but the old flossing head seems like it gets between teeth better. The app is a bit wonky, but I bought this for the brush and not the app tracking.

    Never realized how poorly I was brushing! This coupled with the app has really revolutionize the notion of clean teeth. We thought about the lesser models but the higher model you go the more they add in features and brush heads so it is really a better value!

    This a great electric toothbrush! I have had older models of Oral-B electric toothbrushs and this is by far the best one yet. The clean feeling you get from this toothbrush is amazing. Threw the Sonicare in the trash once i got this one.

    great toothbrush recommended by my dentist. love the app features how it tells you when to move onto the next section of your teeth and the rating it gives on your brushing. I also like how you can set reminders when the brush head needs to be changed.

    I never thought I’d spend this much money on an electric toothbrush. But, at the recommendation of my periodontist, I got one and it changed my life!! It’s totally worth having and definitely money well spent!
