I can really only give these vertical blinds 3 stars because I’m not happy with the way the pieces get caught on the split in the rails when you slide them to close. Not a smooth closing and I wonder how long it will be before the small plastic piece breaks when your trying to close them. Have tried different techniques but it still gets caught on that split. Very confusing directions. Other than that the blind is very good in blocking the sun when 
you need to.
