We had 2 Handy service men show up to hang 2 mirrors on our wall. We asked them to hang them vertical with the 2 mirrors touching each other with the top mirror level with the curtain rod for our window. It took them multiple tries to get it right and now we have many extra holes in our wall to repair and they did not even realize the bottom mirror was not level until I told them, I had to loan them my level gage to make it right. Eventually they did get them hung on the wall correctly.
