If I may chime in.....I got my mirror a few months late because of the equiptment problem the company sustained. So this is not vapor ware as some suspected. I only ordered the driver side so I can only comment on that one. It is the same shape and size as oem albeit maybe a hair larger in the corners. If one is used to the wide angle of the passenger side mirror then you would like this mirror. It has a little more fisheye effect than the passenger side so you see more on the driver side. The outer 25% of the mirror is even more curved so you can actually get a glimpse of the lane next to the empty lane on your left.
It comes with double sided tape for mounting but I used clear silicone as others have suggested for peace of mind.
