When you actually stand in front of the mirror, there's a slight time delay before the image gets out of the way; and even then, it just shrinks into a square at the bottom; the mirror is never fully a mirror. Even more annoying? The reflection isn't great, because the glass is tinted. This isn't somewhere you'd want to do your makeup, unless you really like orange tidemarks.
When the image shrinks - it's still tinted
The verdict? Kinda intriguing if it's just an O'Hare feature. Kinda annoying if they get rolled out across the country. And def kinda bad for your grooming upkeep.
