Customers are saying

Customers often highlight the DiamondClean Smart Electric Toothbrush's superior cleaning performance and the variety of brush heads included for different oral care goals. The long battery life and helpful app are also appreciated, along with the sleek design and pressure sensor. A minor drawback is that the travel case does not function as a charger.

    Toothbrush is great. Wish the carrying case included charging as in previous versions.

    The brush died after 2 years. The button seemed to need to be pressed a couple of times before turning on for about a week. Then it just died. For the amount of money I spent on this my toothbrush should last at least 5 yrs. Very upset bc this was an investment gone to waste.
