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.

    Had the 1st gen diamond clean for a decade, and it's still not broke. Decided to treat myself to have one for home (this one), and one for travel that's already packed (my previous one). Let me say this toothbrush is one of your life-critical purchases that you will never regret. Bravo.

    I upgraded from Oral-B and will never go back. I my opinion Sonicare is a better clean.

    I was shocked when they said the price at the register..... I clearly thought the sticker said something else. But I thought, my teeth deserve this, I was wrong, no one does. It feels like your teeth are being cleaned by angels with silk brushes.... in bikinis. It’s worth every penny.

    This has been my go to toothbrush for the last few years. Does a great job and always leaves by mouth feeling super fresh and clean.

    Good power and adjustable! You can literally feel a difference after one brush, it’s nice to have that feeling like you just came back from the dentist. The battery life is good and the convenient travel pack is the best!

    My teeth feel nice and happy

    Everything is pretty easy to get the hang of. The app is kind of gimmicky, but it does help you to understand the best practices. My teeth feel nice and smooth afterwards. The replacement heads are nice, other than color, the bristles look and feel exactly the same ( stiffness, and placement of bristles). Vibration intensity is adjustable in all modes, and all modes almost are identical. I keep the toothbrush body very clean and dry, also I remove brush heads after every use. If it’s on sale it’s worth it. Full price is ridiculous. There are some without the tongue mode that are cheaper. Tongue mode is pointless. The tongue scraper attachment in any mode will provide similar results.

    Powerful Cleaning

    Upgraded from a previous sonicare model (healthy white). The iPhone app is a little buggy, recognizes this brush as a lower end model and occasionally tells me I’m using the wrong charger (the same charger it came with). However, the powerful cleaning on this brush is top notch. Teeth and gums feel clean and healthy.

    Although it might seem pricey, it’s worth it. This toothbrush does a great job. The real test will be when I see the dentist. It comes with different brush heads. There are specific brush heads for this model for certain features to work, like the app. There is a travel case included. The app helps keep track of missed areas. My teeth did get a little whiter and are clean. It’s a great quality too. I’d rather have a charge stand than cup that sits on a charger but the cup can go into the dishwasher.

    Expensive but good

    Expensive but so far so good. I've only had the toothbrush for a couple of days but my teeth feel really clean. I had an old oral b and this one definitely takes getting used to as it is somewhat loud and odd to hold until you get used to it. I got this one as it gives you a lot of replacement heads.

    Best electric toothbrush I've ever owned. I had gum disease and my dentist noticed the difference asking me if I have been using an electric toothbrush and flossing everyday. Don't hesitate to buy this Sonicare. Amazing!

    Purchased this Sonicare toothbrush as a replacement for my previous Sonicare. This toothbrush has an app that connects the Sonicare to my iPhone. Using this app, I discovered I was not brushing correctly in two areas and I have since been able to correct this. I'm very happy with my purchase.

    Love my toothbrush. Yes it’s expensive, but my dentist told me I was not spending enough time brushing some spots. Went back to the dentist and he said I was doing much better. I told him about the toothbrush. He said he would suggest it to his patients but legally can’t, but would if he could.

    The best toothbrush out there. I feel like I just had a professional dental cleaning every time I use it. Beautiful blue color with plenty of settings and the glass cup charger is very cool and convenient. It also comes with a rechargeable case for travel.

    This Sonicare is the best one yet! I have a previous version and it worked great, but with the app that comes with this one it take my bruising experience to a new level.

    The app that works with this toothbrush has shown me a lot I didn't realize like the pressure I was using as I brushed to where I took more time and where I needed to focus more attention. I am so happy I upgraded my old toothbrush.

    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.
