The rotation speed can be adjusted as well. I have quite sensitive skin and the normal brush heads are me too hard. I'll have to order my "sensitive" heads.
The application can also be done in the shower or in the bathtub.
One should not only apply to long. That the device turns itself off is very well thought along in any case! One should not overburden his skin namely.
I use to use yet gentle cleaning system (HY-OIL & Phytoactive Reactivating Set BABOR).
Along with the cleaning brush gives the skin a wonderful feeling. Fresh and clean.
Visually, I find the device even more beautiful than the von Braun (which I also have and am also very enthusiastic).
5 stars from me!
