So I've had two sets of tow mirrors in the last 6 months. Both sets have been destroyed by people who can't drive on curvy roads. But my problem is both sets vibrate terribly and makes seeing out of them pointless. Has anyone else had this problem? I have the support brackets in them. Has anyone had the tyger brand? I read on their website that they are built not to vibrate. But it also said that on other sites. Someone please help!
