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.

    BEST TOOTH BRUSH

    I’ve had other Sonicare tooth brushes before but this one is the best I’ve had EVER! It knows the routine by the brush head you have on it add that to the app on your phone and your mouth is going to feel the best it’s ever been. Trust me mine is!

    This is probably the best electric toothbrush on the market, although somewhat too pricey for what it is. I find the associated app gimmicky and not very helpful.

    It's very expensive for the price but well worth it. I'm not too fond of the intervals being shorter than my last tooth brush. Other than that it's an amazing clean feel.

    Excellent brush, switched from a 7800 and you can feel the difference in the motor’s. The bonus of the multiple brush heads just adds to the value of the unit. I have been using the app paired to my phone and it has made me a better brusher.

    This is my second sonicare toothbrush. My first one seem to have created an issue with it being too sensitive when I brushed my teeth. It always would tell me I’m pushing too hard even when I know I wasn’t. Hopefully this updated version won’t have that issue, so far so good and I like the teeth cleaning app is helpful to get a better understanding of how to properly clean your teeth

    Easy to connect to the app, and it's nice to have an actual timer showing how much time you should spend on each section of your teeth as well as real time feedback on pressure and movement. It's a little expensive, but cheaper than dental work.

    There's so many brush heads included that has no additional cost for years to come... Probably 2 .... I will honestly never brush my teeth with another toothbrush again I did one time since I've bought this and hated it. My teeth are by far cleaner and look a lot healthier.

    Excellent toothbrush. This model is quite a step up from my previous two Phillips Sonicare. I liked them and love this one. Has numerous settings which provide a lot of options. My dentist recommends this brush.

    This I bought this toothbrush as a replacement for one just like it that burned out. I really like the app also as it helps to ensure I your mouth is clean. Even though this toothbrush is somewhat costly it’s well worth the price.

    I was hesitant at first buying one so expensive but it hasn't disappointed. I will say I don't ever use the app but the toothbrush itself is great and looks great. Recommend something cheaper if you don't use the app.

    New Sonicare is an improvement over older model

    Replaced an older Sonicare with the new model. I like the six sector timer better than the older four segment timer. Brush is also slightly larger. The unit also comes with a brush for your tongue, and the handle automatically detects the type of brush inserted. A good investment in oral health.
