Greed and avarice

Why the set only one key included (reorder cost whole 14.90 euro!)
and the end caps shown in the youtube video also must be ordered separately
(3.90 per card) can only with avarice or explain greed. (Not even NEN keyring is.)
After all, this set is not exactly cheap.

Also, there are weaknesses in the operation. Does not fit on one
flying one of the whole business with all parts such as O-ring, nut, spring and washer and tail by the workshop.
Here you could all somehow to encapsulate in a single component.
In my Sattelstüze the Achso is so long that I no longer get through the hole in the key.
This would therefore also still nen CM may be longer ...

With two keys and the end caps I could forgive maybe 4 stars.
So I think is required for what is offered simply too much money. Especially for the reordering.
