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.

    Love it. I had a cheap electric tooth brush before this and I can really tell the difference.

    Fancy Electric Toothbrush

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    My husband and I got this toothbrush since we needed an electric toothbrush to keep our teeth in good shape after spending so much at the dentist to fix it. We purchased this set because of the extra attachments in this set. After a month of using this along with the app, I found this helped keep us accountable and truly brush our teeth for the advised 2 minutes. Definitely recommend this product, it is an investment, but I don’t plan of replacing this toothbrush anytime soon. 4 stars out of 5 because of the price point seems to be a bit ridiculous, but you pay for the newest and best, and the app does not allow multiple profiles on the same device. We had to use separate devices to have the brush remember one profile. Not bad if you just keep it for yourself, sharing causes some problems since this tracks when to replace the brush head and adds both users together.

    The toothbrush is great, and my teeth have never been cleaner. The app is not very good, and it has trouble telling where I am brushing in my mouth. The app also only wants me to brush the inside and outside of my teeth but not the tops.

    No, I would not recommend this to a friend
