How durable are these? And the factory ones? I ask, because I used to have a 98 Tahoe with one...the sensor wore out before 25k miles and I had it replaced under warranty...then the replacement wore out just over 50k miles. In both cases, it stopped dimming unless a very, very bright light hit it...and even then it was a lame, greenish tint. I was not too impressed with this type of mirror, especially when it didn't function correctly...there was no way to "tilt" it up, so I was dealing with lights in it all the time at night.
