I put a set of clear view on some time ago i stressed at roundabouts for a while,until i nearly cleaned up a police car..He was not impressed,the exercise cost me $380 + $60 for victims of crime..i lost vision of him because of the size of the items,,, needless to say ,they came off,and i went for a smaller profile set. I liked the units ..but they may need some consideration in city areas and low use conditions.
