    The Philips Sonicare DiamondClean 9700 Rechargeable Smart Electric Toothbrush comes with 7 brush heads and a tongue scrubbing head, an at-home charging station, and a travel case that also serves as a charging station. Also, a smart phone app can be used to enhance your use of this device. I was pleasantly surprised at all of the wonderful features of this electric toothbrush. Just the fact that it comes with so many brush heads is a huge plus. I also liked the brushing pacer, and really love both the charging station and the travel charging case. Charging: Straight from the box, the unit comes with enough charge to use more than once. The instructions suggest that you use it once and then charge it fully for 24 hours. You can charge the unit two ways: (1) The charging station consists of a gold colored base, a charging glass, and a lid for the glass. When charging, you plug in the base and place the glass on the base and place the toothbrush inside the glass. You don’t have to place it in any special position because the bottom of the toothbrush has a solid copper-colored plate which begins charging the unit as soon as it touches the bottom of the glass (as long as the glass is on the plugged-in base.) The toothbrush will beep and vibrate for a second when it begins to charge, so you know it is charging. The glass can also be used as a drinking glass and it has a lid which keeps dust out of the glass. In the center of the lid is an indentation that exactly fits the toothbrush so you can use it as a stand for your toothbrush when it isn’t charging. (2) The travel case has a USB cord embedded in the base and this can be plugged into a computer USB port or a wall plug USB port for charging. When not in use, the cord can be wound around the base and held in place with a detachable cover. A fully charged unit will stay charged for 2 to 3 weeks. You can keep it on the charger between every use or you can wait and charge it when it is low. I asked Philips which method they suggested and they said I could do it either way but suggested I should wait and only charge it when it is low. App: Before use, you should consider installing the Philips Sonicare App on your smart phone. I did this and found it extremely valuable to help me brush my teeth as well as possible. You don’t need to use the app to use this brush, but I found the app helpful. Setting up the app was easy. It found my toothbrush immediately and I began using it right away. Also keeps track of dental appointments and lets you create a report for your dentist if you wish to. Use: When brushing your teeth with the toothbrush, you can select different brush heads for cleaning, whitening, or gum care. There is also a head for tongue scrubbing. You also have a choice of 3 different intensity modes. If you don’t use the app, the toothbrush handle lights up if you are using too much pressure. You have choices of different modes (cleaning, whitening, gum, and deep clean). The toothbrush will beep after a specified time reminding you to move your toothbrush to a new location in your mouth as you brush. In the cleaning mode, it gives you six 20 second intervals and beeps between each interval. (For example, right top, middle top, left top, right bottom, middle bottom, left bottom.) If you use the app, you can connect your toothbrush via Bluetooth to the app and watch the app while it shows you where to brush and for how long in addition to the beep reminders on the toothbrush. It also tells you on the app if you are applying too much pressure, which I found helpful to train me how to use it properly. After brushing, you get a report that shows how well you did. For example, on my first attempt, it showed me that I applied too much pressure a few times and in the report afterward, it showed that I didn’t do well enough on my inner lower left teeth. On my second attempt, I did much better. Also, it asks you if flossed, used mouth rinse, and scrubbed, so you can keep a record of that. Brush heads: The unit arrived with 3 cleaning brush heads, 2 gum brush heads, 2 whitening brush heads, and 1 tongue scrubber head. Both the app and the toothbrush itself will let you know when it is time to replace the brush head. Several of the features can be deactivated if you don’t need or want them. This includes the brush head replacement reminder, the pressure sensor, and the easy-start mode. Pros: Travel Case that doubles as a charger, Multiple brush heads included, Brushing Pacer reminder, Replace brush head indicator, Unique and attractive charging station, Three sensitivity levels, Multiple modes Pressure sensor, App with record keeping and reports, Dental appointment reminders on app, Rechargeable with long lasting charge Although, I didn’t need it, the Easy Start mode lets you gradually get used to the toothbrush over a period of time. Cons: None

    In the box you get tons of stuff! The toothbrush handle itself, several different brush types depending on your preference, as well as a tongue scrubber. There is a small glass cup for rinsing which also sits on the charge base so you can place the brush in the glass to charge, although I do not use the glass for rinsing and the brush just sits in there. It also includes a travel case which can also host a place for a couple extra brushes. To get it going, it’s optional, but you can download the app that tracks how you brush, how well you’re brushing, and where you need to concentrate more or less brush time in areas of your mouth. It also tracks the wear on the brush heads and lets you know when to replace them. The app definitely makes it easier to use an electric brush and helps to make sure I’m evenly brushing. Brushing itself was definitely odd at first coming from a traditional brush. After a few uses, I had gotten used to it and could notice it was more effective than a manual toothbrush. The brush automatically sets the brush mode to the optimal settings for the brush head selected. After a few days my teeth felt cleaner and mouth felt fresher. Only downside to this electric toothbrush, is when you remove it from your mouth, be sure that it is off, otherwise you’ll get toothpaste everywhere! It does take some getting used to and setting new habits, but after day 1, this was no longer an issue. The brush doesn’t feel cheap in the hand, and seems well made and cleans easily. I would definitely recommend this brush if you was looking to invest in your teeth!
