There perhaps has more strands of this new Oral-B brush as the previous, but they go faster trumpet. The strands are not planted at right angles to the head of the brush (as was the case on the former), but are already with open angle outward. As already in wear phase. In other words, it is a case of "planned obsolescence," a well-studied system by which a product wears out or stops working prematurely (like light bulbs). For that renews faster replacement. The swindle is especially rough here as the planting of the strands to the outside is clearly visible on the new brush. The wear is accelerated and proved the scam.
