and I can also confirm cfg89's statement about this mirror's level of WIN for the buck. You can see all the way up to your peripheral vision with this thing, with the added bonus of seeing yourself plus everyone else in the car (which admittedly took a day or two of getting used to).

I don't have any side mirrors at all and use this as my exclusive rear view mirror without any problems at all even during rush hour traffic. I have no problems at all judging vehicle distance in the mirror as I can see the entire rear periphery of the car and judge whether cars are in front of or behind the B or C pillar with ease.
