    This is the best toothbrush I ever had. I have had electric toothbrushes before but this one takes the cake. It feels good in my hand and looks great in my bathroom. Having a smart toothbrush that tells me how well I brush takes the cake. I recommend this to anyone who can afford it.

    Great toothbrush and smartphone app idea! I am a technology nut, so I thought this was a cool idea! I love the app and for parents, with kids, it can be a great idea to monitor their brushing habits!! It feels as if my mouth is cleaner and I am sure that it is!

    If you are in the market for an electric toothbrush, you need to get this one. I have had different Philip toothbrushes for years, and this is the best one by far. To start it is much quieter than previous models that I have owned. I really like the versatility because it provides 3 different settings. All you have to choose is your main objective when it comes to oral care. I also really like the glass that it comes with to charge the toothbrush. Overall, if you are looking for a quality electric toothbrush, I would highly recommend the Philips Sonicare.

    A Truly Hi-Tech Brushing Experience

    I never thought I'd see what I'd call a hi-tech toothbrush, but the Sonicare 9300 is definitely cutting edge. The Sonicare 9300 is a Bluetooth connected devices. Its "smart sensors" allow you to see if you are pressing hard enough (or too hard), as well as ensuring that you are covering all of the areas in your mouth. There are also different kinds of brush heads available for the Sonicare 9300: Plaque Control, Gum Care, Premium White, and TongueCare+. Each type of brush head is automatically detected when put on the base unit, so that the brush knows just how to opperate with each specific brush head. It will also keep track of when a brush head went into use, and remind you when it is time to get a new one. After just a short time with the Sonicare 9300, I feel that this toothbrush will lead to much better oral health.

    There was an issue with the floor manager, Melvin. Price was mismarked but he didn't seem to care and seemed he was annoyed that I was buying a $200+ toothbrush. It's the principal of the wrong price being posted, just $10.00.

    After using this toothbrush for a week I noticed that my teeth feels very smooth and clean. The coolest thing is the bluetooth feature allows you to keep track of how long you should brush each section.

    This toothbrush is REALLY great. Their is an app that lets you know when your heads are old, how ling you have been brushing and what areas to work on. The intensity of the brush is crazy! Even the softest setting sends toothpaste flying everywhere if I open my mouth even a smidge.

    Makes brushing fun

    This "toothbrush" has cool technology and is more like something you'd have a dental hygienist use in the office during a cleaning. That makes brushing much less a chore, and more of a joy. Connecting to your phone via Bluetooth technology, the phone keeps tabs on your brushing effectiveness and regularity of use. The only thing that it won't do (to the best of my knowledge) is store your brushing sessions for syncing later. So to track your cleaning progress you seem to need to have your phone connected to the toothbrush with the app running while brushing.
