What bothered me about other electric toothbrushes, was the noise that came close to a vacuum cleaner. This sonic toothbrush is almost inaudible: A low hum is not charged my morning sensitive ears. The built-in timer switches every 30 seconds a small holding signal to the toothbrush, then you have to change the quadrant: top gear outside top teeth inside, below the same. Downstream I brush then the chewing surfaces, tongue and palate.
Something bothers that the toothpaste easily running down the smooth device while cleaning - something roughened the surface would have been more practical. The replacement of a cleaning head is easily - even though the replacement heads unfortunately are extremely expensive.
The Aukkulaufzeit, assessed after 4 weeks use: I have re-charged once the unit full 24, and for 4 weeks I brush now. Let's see when the battery should be recharged. I do not know after this experience, why I should leave the charging station, which is pleasantly small, permanently connected to the network, as it describes the manufacturer in the instructions.
My dentist has recommended to me, and so far I think it's really great device, even if the investment is quite large - but the painful plaster slits by excessive and intense brushing now belong to the past, and it's worth it to me.
