It was installed without problems. The size of the mirror part is also almost equal to the genuine product. The finish of the plating is also good.
However, in the genuine product, the screw part is M10 and the shaft part is φ12 mm, but in this product, the shaft part is as thin as φ10 mm. I do not know if it compares, but it looks a bit poorer when compared.
But I am satisfied.
