1. cleaning performance: This is outstanding, even after normal cleaning program (2 min.) Very clean feeling. The interdental spaces are cleaned very well: 5 stars
2. cleaning modes: As noted above, the cleaning performance is very good. The different modes cater for special requirements, for example, intensive cleaning (3 min.) Or a program for cleaning the tongue. However, the toothbrush by running at most times slower or so. The fact is that nevertheless always performs the same movement. For as much variety of programs, but by the more or less real advantage by: 4 stars
3. Additional functions: These are of course not comparable to other toothbrushes. On the one hand the different brushing modes, on the other hand the Bluetooth function. The connection with the Oral-B App and its functions are worn and very good at the same time. Something for high-tech fans;) Also the SmartGuide served its purpose and serves as a timer and gives an extra character (next to the toothbrush itself, which blinks red) when you press down too hard. The toothbrush itself also has a timer and flashes every 30 seconds. In summary: Timer very good; Pressure sensor very good and very useful in order to preserve the gums; Bluetooth: awesome, absolutely innovative, therefore 5 stars
4. Accessories: Appears very high quality, in particular the Transport Case. The bag for transporting the charger a quality image. The only complaint is that the toothbrush has a built NiMH battery and no Li-ion battery. These tend to be worse. With such a high-tech product and at such a price, I can not understand this, hence 4 stars
Since the battery is fundamental to an electric toothbrush, I forgive, despite the otherwise everything is great 4 stars, because the battery is only a NiMH battery despite the price.
