I have the bracket mounted with the supplied screws. Remove the screws (4x) were long enough recessions that the screws are too short, I can not confirm nor understand. The license plate - Euro plate acc. DIN 74069 (width: 520 mm, height: 110 mm) fits absolutely perfectly with light pressure to slide the plate into the provided groove. Again, I can not confirm recessions, which fit to suggest that not the mark in the groove. The plate holding actually already in the groove bombproof, nevertheless additionally fixed despite located on the mount, an adhesive strip of the indicator. At the latest use of this tape can not move the indicator. The holder is not thick / thin like a normal car license plate holder - and here I leave it not apply to the license plate projects now.
Conclusion: One can easily mounts on the car mount without the mount wobbles, the license plate sits just fits in the slot and does not move. The supplied mounting hardware is also ok, but could be extended by 4 screws. Last but not least: The brackets simply look fabulous I can with a clear conscience recommend.
