    Why do you need an app to brush your teeth? I asked myself the same question until I actually tried it. It helps ensure you brush all critical areas of the mouth. Now I don't want to brush without it. Overall, the toothbrush is great! I took it traveling with me. Took a little more room in the bag than I was used to but overall a great experience. I really like the sensor that tells you when you are pressing too hard. If you have the money and need a new toothbrush, it's worth it.

    I purchased this on a whim and am SO GLAD I did! I have loved all of my Phillips Sonicare products but this one beats all of the previous ones hands down! My teeth are even cleaner and my gums as always look amazing. Our hygienist always comments on my lack of plaque and tartar on my teeth and my great gum health. I tell her it is the toothbrush. I really love the charging glass. Looks classier and works just as well as the other chargers.

    I just went to my dentist and they told me i needed to brush the back of my teeth better. She recommended the oral b because the head is easier to maneuver

      Hi James,
      thank you for leaving this review. We're sorry to hear that the performance of the DiamondClean is not what you expected. This device comes with smart sensor technology, which makes it easier for you to perfect your technique and get a complete clean. We recommend connecting the device to the Sonicare app if you haven't done so already, to be able to see real-time feedback on your brushing. The location sensor of your toothbrush tracks your coverage and transfers this to the app, so you can see exactly where you've brushed, and where you've missed. All of this is to help you cover 100% of your mouth, 100% of the time. We hope this is helpful.

      If you have any further questions, please feel free to get in touch via social media. We’re available 24/7 on Facebook (https://bit.ly/3yBQ1qb) and Twitter (https://bit.ly/3g2fXmw). Alternatively, you can reach out to us via the contact page on our website. One of our colleagues will then try their best to help you further.

      Hope to speak to you soon!

      Kind regards,
      Philips Consumer Care philipsglobal

    when first opened I was surprised by the quality, it looks and feels great. Was a bit hesitant to use at first but after a slightly messy start I got the hang of it. I downloaded the app to my ipad and used it for the first week just long enough to get used to the toothbrush. Would definitely recommend purchasing this.
