I got the Grand Aero mirrors and am not altogether happy with them. Best thing about them is that they are attached to the standard mirrors, and of course fold with the standard mirror. The problem is that the optics are just not very good. A lot of distortion. They work OK for general trailering, but when I tried to back the trailer into its garage, I couldn't do it with the Grand Aero's--too much distortion and backing into the garage is a precise business--I want to center the trailer in its stall within a couple of inches. Put the McKesh mirror back on the driver's side and it was a piece of cake.
