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 upgraded from a 9300 when it started having charging issues. Got this on a discount at just over $200 and it comes with far more features than the 3/5 series, including Bluetooth connectivity and a tongue brush.

    Powerful, cleans well. Really like the navy blue color. Had my prior Sonicare toothbrush for at least 5 years. It stopped working so I purchased this one. I’m spoiled with this toothbrush. Highly recommend.

    Expensive and worth it.

    Although priced a little bit on the high side, I believe all of the additional features are worth it. Plus, the color matches almost perfectly with my new Galaxy S20 FE (cloud navy). Hey, who says guys can't accessorize.

    Love! I’ve had this for almost three years and it’s still working great! I misplaced the tongue brush and it’s hard to purchase another so I don’t use the feature but other than that still works amazing!

    Didn’t think I would be impressed with my new toothbrush but I was. This toothbrush connects with my phone and lets me know where I missed, if I brush to hard or rushed over a section. Thus will help to keep my money in my pocket and make my dentist happy too.

    I love that the brush allows you to change the intensity. The various modes all of to address every angle in which you can clean your mouth as a whole. The carrying case allows you to charge other devices in the event that you’re limited to outlets.

    I am so glad that I purchased this. It is much better than the essential one I had several years ago. It is also much more expensive, but I think it is a good investment. The quality is also very high.

    I purchased this after my diamond clean 9 charging base malfunctioned after two years. I don’t use the app much even though it is very useful, the haptics are great and notify you if your brushing too hard or fast without the app which I find very helpful

    Teeth are feeling great after use (never had an electric toothbrush before). Well worth the money, but really I think this was so much because you get a lot of the replacement heads. So it made sense to purchase

    Ok, you probably don't need to spend this much on a toothbrush but it really does the job and looks attractive too. I tend to like gadgets so I am impressed by the smart technology and the charging in the glass.

    It’s 100% worth the price. This version has the most bang for your buck. With 8 heads ($100 value at retail price) it’s a no brainer! The brush is absolutely amazing and I would pay $300 for just the brush!

    Bought my first electric toothbrush couple weeks ago and really enjoy using it. Though to be quite honest, I don't use the app and occasionally use the different modes that the device offers.
