Order was duplicated, so 2 arrived. Opened one and could not get it to fit as it failed to clip on. Tried to adjust the flat pieces that go behind the brackets to facilitate the actual fitting clips-made no difference. Checked against my broken mirror and the new replacement ones are approx. 4 MM bigger around the whole circumference, ie wrong part sent, and the glass was holding it off, so clips could never engage. Only had a refund for they unused one, even though the wrong ones were sent, because I had damaged the fittings! Eventually got the correct one from thewingmirrorcompany. Clicked straight on.
