The far left shade kept having to be adjusted because it wouldn't sit uneven.  The shades are a little off color and not as clean looking as I would like.  Also two of the shades had nicks in them.  I was able to turn that so you couldn't see it, but I couldn't return them because I only had a limited time with the installer and everything else was here.  Also any dirt or dust shows in the bottom.  Installing it downward may have fixed some of these issues.
