I've had them a week. Had to re-install the front visors because I did them wrong. Broke some small pieces off trying to force them into the window channel. As far as extra noise, they probably add a little more noise while the window is open or closed, but not enough to make me think about it. The back visors don't sit perfectly, but are not really noticeble anyway. OK, I have no regrets buying them. ( $100.00 even from AutoAnything )
