The design of the brush itself is not much to say: it is an Oral-B brush is it shows the first blow Wave, they have, on that never made a real effort to improve or innovate when the shape or even the handling of their brush.
Its price remains in those of the market, "consumables" too, even if the supplies of electric toothbrushes come overwhelmingly from the outright extortion.
Efficiency Level one is exactly the same kind of benefit as for other Oral-B brushes range input, hence my question, why spend more for this model? I do for myself, no justification for its price because their effectiveness is the same.
