    It’s an upgrade from the previous model I had and with the app being accessible, it’s easy to use and for you to keep track on your brushing habits.

    Love the design. It doesn't take up much room on the bathroom shelf and the buttons are flush with the handle so no more getting toothpaste into the crevices and making the buttons not work. Love this re-design of the handle. Holds the charge a long time so I usually don't even have to charge it when traveling,

    Love the toothbrush, made a noticeable difference on my teeth after about a month of use. The app is a little off with how long/where I am brushing but it still helps. The travel case is really handy and I love it.

    Wow. Bought this to upgrade my old phillips which was about 5 years old and still working. I wanted to jump the app based iq sense and im glad i did. I got it when it went on sale and the same price as the previous model. There is so much to say about waht this can do but you can just google it or check out youtube for some in depth reviews.

    I really love my Sonicare 9900. I have always been a poor brusher and finally decided that I would take my brushing more seriously after another poor dentist visit. I continue to have that fresh from the dentist clean mouth feeling since using the sonicare. I like that it has sensors and can tell you if you need to focus better on a certain part of your mouth, times you and lets you know when to move to the next section of your mouth and gives you hints on techniques such as moving too fast, too much pressure etc. I have only had it a short time now but so far I do think it is worth the pricetag.

    Love how it keeps up with your brushing routine! I create a challenge to keep everything in the green as far as brushing twice a day and for the recommended time frame! Always a dentist clean feel afterwards!

    So far it has not broke on me yet. I do get a slight change on vibration intensity once it has been on for about 30 seconds. Other than that my teeth feel cleaner. Powering on the device can be tricky at times since it is not an actual button. Once you get used to it the experience becomes way better.

    I have tried other toothbrushes out there and this is by far the best one. The improvements from the previous generation are worth it as well and some improvements to the app have been made. If you are reading this and still happened to be in the stone age then it is time to upgrade.

    I've been using this for about a month. It works great. I used to have another brand that didn't seem to clean. This sonic brush is powerful enough to get a consistent clean. Definitely worth the money. The battery life is very good and the app is helpful.

    Love everything about it. The Sonicare prestige is a cut above the 9700 and down in the sense of quality. It’s a one in all product.
