Customers are saying

Customers find value in the DiamondClean Smart 9700 Rechargeable Toothbrush's cleaning capabilities, variety of brush heads, and user-friendly app. The long battery life, ease of use, overall performance, travel case, and design are also well-received. However, some customers find the price to be high, and a few have noted sensitivity to the vibration and occasional Bluetooth connectivity issues.

    If you are considering buying this model I would recommend the Diamondclean 9300 instead. It is exactly the same. The only difference is that the 9700 comes with more replacement heads. I do love it, though!

    I decided to replace my current sonicare toothbrush - Diamondcare - which I’ve had for several years. After using the newest 9700 model for a few weeks I must say I am obsessed! I love the smart technology and app which has helped improve my brushing skills. I highly recommend this model. If you can get it on sale it’s definitely worth the investment. My teeth feel so extremely clean after using this toothbrush.

    I love these toothbrushes. It does clean better than the old Sonicare diamond clean but the app is pointless and I stopped using it after a week. It's stupid expensive but I do value my teeth and believe it is a good investment in that regard. I'll probably buy my wife one too.

    Have fun to learn how to clean my teeth ... how to move and where to be and if I pressure too much ... it's a nice app to talk to your tooth brush ...

    Expensive, but truly is the pinnacle of toothbrus. Gives you an intense clean that is second to none. Has a timer and app and several modes for different types of cleaning.

    I have the prior version of the diamond clean loved it. This brush is way better. The brush works way harder to get teeth clean. the app on the other hand is gimmicy.
