First off-we love the mirror, that probably was one of the problems. It is not the easiest to hang vertically. The brackets on the back need to be straight up & down to hang easier. Not at a slant. Plus one bracket was alittle higher than the other side. My husband measured & leveled alot. Then when we put with our new vanity lights-the globes hit the frame, again we Love the mirror, so lowered the mirror some more as we loved the look and wanted to keep the mirror & lights. The mirror is heavy duty- & beautiful. We just kept at it to make it work! Very happy now that it is up!
