    I've been using a Sonicare for years and it was time for a new one. The pressure sensor takes a bit to get used to, but overall I really like the toothbrush. You can easily travel for a couple weeks and not run the battery dead!

    Bought the brush for my wife as a valentines gift. She really likes it. Its easy to use, the cleaning options are great, and the app to track brushing makes it a 21st century marvel

    Regular standard brushes are a thing of the past. Take care of your teeth, pay the price to get this great brush than paying for a dentist to carve up your mouth like it's real estate.

    our family switched from the round Oral-B toothbrush system to the Sonic care system and I was not disappointed. I believe that this system cleans your teeth while massaging your gums better than Oral-B resulting in great dental checkups.

    Never understood why you would need an electric toothbrush, until I used my wife one. Could not believe how clean your teeth feel after using. I bought one right after I tried it. Excellent product, have not used the app for it yet.

    I purchased this toothbrush as a gift for my wife. At first she was hesitant, thinking that im implying that her breath smells, but that was not the Intension at all. Later she used it and was very enlightened on how great the toothbrush was!

    This toothbrush is amazing. Comes with an app for specialized brushing like pro clean or white plus. Also tell you when your brush head should be changed. That mixed with specific goals would like to achieve make this toothbrush fire sticks

    I got this for Christmas. My next dental appointment was half the time it normally takes. It makes my teeth very clean. I like being able to see my progress on the phone app. I highly recommend this toothbrush.

    Nice cordless brush. A bit overpriced in my eyes but does what it says. It would have been nice if was able to charge the brush while in the case for travel as some of the other models from Philips.

    This toothbrush has Bluetooth and connects to your phone to guide your brushing. The app will tell you if you missed any areas or if you need to brush more and where. I'm not crazy about the cup charger though.

    I purchased this toothbrush for my wife so that she could take care of her teeth after getting her braces off. It has been a great product and the app really allows her to know where to focus her efforts and/ease up the brushing.

    This is a very nice and elegant tooth brush, but for $200, it was just not practical for me to keep. I might buy one again some day down the road when I truly run out of things to spend my money on.

    Surprised at the stark contrast of using a toothbrush that has an app to tell me where, how, and how long to brush vs not using that. The results are amazing.
