Not bad is here: not good.

In one of the two knurled nuts the threads are cut wrong with my copy, which then results in that the adapter is not sitting when tightening exactly perpendicular. Thus, the application is still quite limited. Emotionally, I would want to give rather two stars, but the rating "do not like it" does not hit the core and all. As it so an adapter is nowhere here in the shop, unfortunately nothing remains but to bite the bullet.
