For vibration: Since you can not tighten the rubber tabs so, but if you have not a long, horizontal and somewhat rectangular mirrors (have a Doblo 2010 with slightly tilted and vertical mirror design.), Then a vibration is unavoidable since. He is then to fix only at 3 points.
In addition, the large mirror has a much too strong magnification to my mind! Here probably a practical test was never made: The view of my caravan was a joke! Luckily I did not have him go too far ...
Blind Spot made at least his job, making you even saw something - therefore one star more. Otherwise, I just looked in my mirrors normal, where I actually had the width of the Doblo everything in sight - fortunately. Seen in the mirror had more tokenism than anything else. Nor could omit degrees ...
The assembly was not a problem. A matter of 2 minutes.
My tip:. Who has large vertical cut mirror, which still have a slightly sloping design, which I do not recommend the purchase, because only 3 of the 4 brackets on the mirror keep u thus more vibration is consequently => no view. The powerful zoom of the main mirror is unnecessary for me u. Incomprehensible!
Conclusion: Sent back and will probably buy me soon the expensive competitors ....
PS: If my review was helpful to you, I would be glad about answering "yes" in the end very. Thanks.
