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.

    I love my new toothbrush. My mouth and teeth have never felt so clean (other than when leaving the dentist). I like the three different intensities. I have a hard time telling the difference between the different settings. The toothbrush is elegant and feels great in your hand. It is just a little pricey for what it is.

    Love this brush! It is so quiet yet it is so strong. The app makes you notice so much more about brushing your teeth.

    I’ve owned other versions of this toothbrush, but this is the most advanced version. It has many attachments and an app that guides and gives brushing advice.

    Had an older model for 6 years! Decided to splurge on Top of the Line. Intelligent design recognizes the brush head and automatically adjusts for proper speed and intensity. Comes with a great variety and number of brush heads. Looks are Elegant! My teeth were Whiter in 1 Week! Makes brushing teeth easy. App is OK. Basic. But it does help and keeps track of how often you brush.
