Installed my convex Broadway mirror last night ...its a spring loaded clip on style . It looks great , not tacky looking, highly polished - no distortion, doesnt vibrate in place and the 270 mm convex version just fits in between the visors if you have it centered properly. So when somebody puts the visor down on the passenger side its not going to hit the mirror or vice versa. Field of view is hard to explain but its about 35% wider than the stock mirrors field of view . I can actually see out to the rear passenger window on that side of the car. Would highly recommend this mirror.
