I had looked at me some wide-angle mirror on Amazon and was quite indecisive. ultimately it has become this .. gut feeling. The mirror came quickly, was neatly packed and the processing is absolutely fine. Solid. Nothing to complain about, no attraction. I think if you do not let the fall, or running at full tilt in front of a wall, the mirror will last longer than me. Which, of course the most important is: the all-round visibility: absolute plus. My car is quite long with six side windows. Since you have already look good if you want to change tracks with the mirror .. I really feel to get a good panoramic view of the situation behind and back beside me. A bit of getting used to it takes maybe because all objects look a bit small, but that is in the physics of matter and is ultimately always the case. A small shoulder view I need theoretically still, because I can not look so out of my side window (which for a smaller car but might be possible), but very well to the rear and from the side windows of the second row of seats. So slightly surprised me because now no more. CONCLUSION: I agree with the person who had called for here, which is part of such a mirror in every car! This here is nothing special, but it does what it is supposed for a small price very good.
