The bit holder, so the head itself in my opinion is quite high. Bits hold bombproof, but can be easily ejected. To which I think it's really good that the black cover is loose. Thus, one can stabilize everything and screw still the same here with one hand.
I'll try to head to judge something, perhaps a bit hilfts.

Supplement 28.11.2013
Today I was in a hardware store and had accidentally seen exactly this bit holder there. Spontaneously, I grabbed again to (7.99 euros -So cheaper than currently here on Amazon). There were a total of six pieces on the shelf. I have all tested on said sloping head. Only a single seemed "quite OK". Thus, I am convinced that already has something goes wrong in the production (in the truest sense of the word).
Since this quality is therefore normally I go from 3 to 2 stars.
