A Original part comparatively favorable levels, but with the need to make concessions in quality. Vibrations that occur during driving transferred to the mirror (joint and glass), which thereby Mitsch beckons. The technology, heating and el settings. But works einwandtfrei. Who his astra only as a commercial vehicle looks and wants to fix low self harm because of car value a repair with expensive original parts does not justify that can safely rely on this product. Otherwise I would recommend to take up an original part. I hope I could help with my experience
