Ürigens the adapter is an original KIWI adapter.
I have thrilled the adapter for a few days in use and am.
I've found the note in one of the largest English-speaking forums Photo of dpreview page.
And what is there generally recommended is very good.
At first I was skeptical:
If the adapter is as good as the original, and why is there not a single vote here at Amazon?
But already when unpacking one is clear:
Quality workmanship and the handling aspect as the original (44 Euro compared to 18 Euro)
therefore receives the adapter from me 5 stars.
