The kidneys are made cleanly and precisely. The exchange was quite simple.
However, there are 2 things to complain about, which is why I forgive only 3 stars:
1. The kidneys are matt black - that would be like should note in the description (there is the kidney that is also in glossy black).
2. In the online shop of convertible style kidneys offered much cheaper. For a slight surcharge would in principle no objection because the dealer must pay Provosionen. Whopping 15, - EUR difference are quite Audacity of convertible style!
