I have had the blinds for 18 years. They work fine and I wash them in my bath tub with a long bristle brush. Barely drain them and rehang them. The noise is dealyt with by putting them "UP" when you travel. I even have them across the front windshields for privacy when parked and I leave myself a note to make sure they are raised before departure.
I would prefer the closed cell day and night shades but they weren't affordable when I installed the blinds. I am only saying that blinds work fine and are maintainable.
