I think I would have liked it a lot more before my eyes start to age. When you need reading glasses at eye-to-mirror distance and your eyes don't refocus from whatever you're looking at through the windshield to the mirror at the speed you'd like, it loses some utility.

At night, I really like that it dims the brightest headlights behind you far better and quicker than the auto-dimming mirror part does.

Best is that it is in addition to the auto-dimming mirror rather instead of it.
