at first I was upset because it was falling all the time when I regained my car I found him on the ground! but once I managed attachment (it was there 1 month) no worries it holds well, it is smaller than a real mirror, but large enough to see baby behind. for attachment I have cleaned and dried my windshield, pushed in the suction cup and be careful not to skip the step of turning the dial serrage.du blow for the price I'm satisfied!
