We have had velux windows and black out blinds for 20 plus years and they was great and worked perfect. We recently got new velux windows and ordered the blinds to match and the quality is not the same. They was easy to install but when you close two out of the three that we purchased, they do not shut correctly with a slight gap on one side which lets some light through and the blind is all wrinkled on the same side. We are disappointed in the quality and the fit, the old ones was much better in all aspects. Thanks
