Yes I love 1 2

a star less just to the absence of seeing the charge level that I consider useful because it does not feel brushing after brushing the level of pulsations down when the battery discharges before ending up off (LED is present on the competitor models it seems).
Otherwise it is a wonder: a constantly renewed feeling fresh after each brushing teeth perfectly smooth and I imagine totally clean. Not aggressive to the gums, and if there is a sensitivity mode brushing "sweetness" (I was using mostly at first).
The signal and interrupt every 30 sec. for brushing zone change is unnecessary in my opinion and even gets a little painful in the long run even if you get used to.
As "slim" is really nice in hand, in addition to being aesthetically pleasing.
Should we change the brush when the bristles "indicator" are entirely faded or when they begin to whiten, it is not clear ...?
