The last few months my schedule changed and I'm driving in the dark now. The auto dimming mirror does not function as expected, it is too slow in response to prevent glare and blinding from vehicles behind me. By the time the mirror decides to dim I'm already blinded from the glare and can no longer see what is in front of me. Also, since it does not dim to the edge I still get blinded from the glare around the perimeter of the mirror (there is no way to adjust this to prevent it). Since this mirror is also "rimless" (no plastic cover on the edge) the polished edge causes light refraction thereby blinding me in daylight. Currently the only way to prevent glare from the mirror is point it down to the floor rendering useless and dangerous.
