It has a pressure control feature which the pulsation will stop when too much pressure, in addition to running noise changed. So you know that you have to reduce the pressure.
A short stuttering sound reminiscent in 30 sec. Intervals to brush all 4 quadrants of the same length.
The brush ensures a very good cleaning. Loosens plaque and cleans him off ..
Again and again I find astonishing how thoroughly electric toothbrushes remove plaque, you can feel really how clean your teeth are when you turvy with his tongue. From such a result, one can at a manual toothbrush only dream.
The battery lasts about 1 week with daily use.
I am completely satisfied.
