The change from brown with round brush was a bit strange, but I got used to it quickly.
The teeth feel smoother (like right after professional tooth cleaning). Gums acts satisfied with the overall situation. Optics acoustics and haptics are ok, and I have nothing to complain about at the pure thing (what is with me rather rare). Would I buy me directly again.
I have (after two weeks) the impression that she has the ugly deposit formation by too much tilting + coffee in the handle; I update this review after a few months again.
Replacement brushes are quite expensive, but keep long because they do not scrub - and the 2 month are a delicate nothing compared to conventional dental bills.

** Update 5 months later:
Furthermore, tooth discoloration caused by nicotine and coffee, but much more slowly than with the old toothbrush.
