Well protected and packaged noble toothbrush arrived home with me. Oral-B lays next to the toothbrush at even 5 different tooth attachments. Unfortunately, the toothbrush came with me to empty, which both the battery harm but also they must first be charged, and that takes a very long time. For me it was almost 24 hours on the charger until it was full. At the time one can load the Oral-B app on his smartphone. When you start the app for the first time, it shows a detail how to connect the toothbrush now with your smartphone. And the great thing is that you have to make only once, just start only Bluetooth and the toothbrush looks for their smartphone. Who is still does not have a smartphone not excluded from Oral-B, the toothbrush works alone and shows the time on a sperat included screen. But the app will track all that you press down the seconds to determine about how many times you brush if you have not just a plaster series whether to brushing the teeth at an airport or in a foreign country. There are badges, and Motivate! In addition to time dressed is a display on the smartphone, also running through messages, so the brushing flies by and you start then totally informed in the day, weather, the app also. If you press too hard, however, this is one with a red light in the toothbrush made optically clear, the app displays a red circle. And you should not even take your smartphone to the bathroom, there are just as described above, an extra display in the time and Smily are displayed. The toothbrush is also able to store up to 30 brushings and later transferred to the phone. In addition to the standard cleaning program you can also select still tongue cleaning, lightening, etc.. The rotation speed is very high which I find very good. All in all, I find the brush a new great experience teeth and makes it so even fun. Only which is a shame is that the battery can not be replaced.
