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.

    The rod at the connection between the fuselage and the brush head comes out, the vibration is abnormal and the noise is particularly loud

    This is a total game changer! I have been with Oral B for years and decided to try this Sonicare. I love this toothbrush and the app that goes with it. If this was not on sale-it would be an expensive tooth brush, but worth the price on sale.

    I purchased this model as a replacement for a model that lasted 15 years. Works great! The bluetooth component takes some adjustment to set up and get use to. Not certain if I'll use all the features but handy to know of all the handy options available.

    I love this electric toothbrush. It has my teeth feeling like I just got it cleaned at the dentist. If you are on the edge about spending this much money on a toothbrush, I say it’s worth every penny. There are a variety of modes you can put it on and it really does leave your teeth feeling clean.

    Worst experience I have ever encountered as a consumer - I returned the used toothbrush to an associate and was told a manager was not available but would contact me, I still to this day did not here from management at Best Buy. Just disgusting that I received a used toothbrush with many of the parts gunked with funk & toothpaste. I still tell anyone who will listen. Sad the disrepair in customer service.
