Dechien,
I didn't specify the size / curvature. I just took what they gave me.
I agree with Dan. These mirrors are better than a standard convex mirror. They cover more area. The fit & finish is a bit of a compromise, but only for us anal types that get inspect things to the point of bumping our noses into it. From a "conversational" distance, you don't notice the edges at all. The increased visibility is worth the trade off, IMO. And, in the end, if you don't like them.... take'em off! It's a reversible mod.
