Compared to a manual toothbrush gives a good cleaning performance - the teeth feel after much smoother on. This version of the toothbrush has the deep cleansing brush head over standard heads by four yellow special bristles differs that are clean in the interdental spaces. This actually works, but not entirely replaced the floss. There is probably also depends on the individual tooth spacing, which differ from person to person. The performance of the toothbrush remains constant over the specified week and only for stays of just before the necessary recharging of the batteries. Overall, however, I am satisfied with the toothbrush. However there is one star deduction, namely for the battery: This is - as so often in electric toothbrushes - a NiMH rechargeable battery, so no modern Li-Ion battery. So you should always fully charge and discharge it (memory effect), although in the instructions that intermediate charges are possible. And here comes the surprise: Charging time for a full battery charge 22 hours
