Technology from the previous century

I bought the mill due to the positive reviews.
I wanted to have a more convenient way with my NIVONA Espresso machines want to change the coffee sort.
For this I must make the bean compartment empty namely every time.
In addition, I had promised me a fine tuning of taste, because the fully automatic "only" has three grinding stages.
The mill was delivered quickly, so unpacked and after reading the manual.
Now that there's not much to read, except safety instructions.
Especially for use of the mill in practice - nothing.
Well, for that there are indeed the Internet.
The mill was first introduced grind with 500g low espresso beans and adjusted the timer on 8g.
Thereafter, with quality espresso beans [Marter Mill / Gourmetroesterei etc.] tries to achieve a freeness with which the Espresso at least equally good tastes like from the machine.
The wheel without the Index HOUSING is a real problem that the fineness apparently nonlinearly adjusted and extremely impact small changes.
What can I say, it was impossible to achieve a reasonable espresso.
After I had milled about 1kg beans, I gave up.
Either the coffee tasted thin as dishwater, or he tasted of banana - really, or was he simply only bitter and inedible.
The pads were ejected from the saw part perfectly, just the taste this was not true.

Conclusion:
For a fully automatic NIVONA unsuitable.
For the princely sum technology from the 60s.
