1) The brush head has longitudinally the same shape as the original, in the transverse direction, the Philips brush rounded (in the middle of the bristles are highest, to both sides taking the bristle height from), so that the original brushes cause a very pleasant and gentle cleaning sensation , The replacement brushes are not rounded in transverse direction and call a normal flush feeling out, as one is accustomed to manual toothbrushes.
In addition, the replacement brushes are transversely, especially on corners and edges on the teeth more difficult to maneuver than the originals.
2) The bristles of the replacement brushes seem to me a little harder than that of the originals to be.
3) Most do not like about the replacement brushes that not all sit over the entire period of use determined on the electric toothbrush, but often resolve while brushing your teeth more or less of it - especially when doing heavy pressure is applied.
This may be reduced by less pressure or even avoid them altogether, never occurred in my original brush against it on (to my toothbrush was just a brush head, and only I can tell).
Also, I have often held the brush head while brushing your teeth, which is also possible. So you can for this deficiency, but does not occur with all replacement brush, offset, which is also a solution for the low price.
As I said, with little pressure when brushing the problem is low and partly it vanishes completely. Some brushes had the problem, so you can not say that some replacement brushes have a good clamping (as the original brush), others less good and some have a little good clamping. This is probably due to the low price.
4) The price / performance ratio of Chinese replacement brushes is optimal, so that everyone can replace the horrendously expensive original Philips Brush extremely cheap by this and thus make use of these good electric toothbrush.
5) There are now these brushes in the 20s Pack again considerably cheaper, for example, the supplier Purple Giants.
Packaging and brushes look exactly the same, I have still not tried!
By the way: although this is not seen in the product picture of Purple Giants, these brushes have needed by families different colored rings, just like the Carolina described here Meyer PLAKAWAY brush.
