Mirror is easy to install by very strong rubber bands to almost any rear-view mirror. The build quality is good. The Kunstoffumrandung makes lasting impression. The field of view is perfect. Properly adjusted can (passenger head disturbs of course) right still see a part of the front passenger window. Something dark tinted glass. I do not mind.
Conclusion: Price - Quality - processing is einwndfrei - large viewing angle
Negatives: large distortion effect. Afterwards moving cars seem to be stuck in Kofferrraum although they have sufficient distance (getting used to) My old wide-angle mirror had only minimal distortion
