Delivered from Liechtenstein and this within 2 days! Processing acts quite high and the connection and installation only take a few minutes. The mirror is tight and rattle-free, but this is likely to depend on the stability of the original mirror. Fluttery interior mirrors - as they are not rare in small cars - are likely to be overwhelmed significantly with this rather massive Clip-on. The image quality of the camera is quite good, however, the adjustment of the ball joint of the lens is sorely limited. The operation is really quite simple, once you've seen through the "Enter key" left of center is and that you can work through the individual menu items only sequentially and you have to leave every time the menu and restart. The mirror is very dark, which is essential insofar as the mirror as opposed to a normal interior mirror can not be grayed out if one night a "Blender" follows. The real problem are the lush dimensions of the mirror, both in height and especially in width, which - depending on the model - the field of vision can significantly limit. Anyone - like me - is slightly larger it will disturb more than smaller contemporaries can look including her, for Smaller probably have trouble to identify a set of traffic lights on the right edge of the mirror over. Another problem is the sun visor. The front passenger visor can indeed be easily folded forward - there would be even a little "air" - but the driver's sun visor and can not be folded fully forwards. For tall people a problem. Next to the right slide is not because otherwise the camera lens is covered. Conclusion: With restrictions thoroughly recommended, especially if you - as in my car - has a second power supply is available and the power cord can be fixed and virtually invisible embarrassed. The windshield should not be too small and too shallow.
