Have this product about 3 weeks now.  Looks great.  Works great, so far ...but, there’s a serious design flaw in the door in door feature.  If the weight in the front door gets too heavy, the door will shut on you while open.  It won’t stay open.   I had my retailer come back three times to adjust as I thought it was an installation issue.   No.  Not an installation issue.  A design issue.  Makes no sense that you can’t use the door in door feature without the whole door not closing on you.   For this reason I wouldn’t recommend d.
