"I gave a 4 because although they are nice heavy liners, they did not fit the panels perfectly. There is a gap on the top, maybe an extra inch, that I had to go back and gather best I could, but you really can't notice it once they are hung, and the liner is about 1 1/2 inch shorter than panel which is OK for me, but thought it worth mentioning."
"These are wonderful. They attach easily to the bamboo panels and make a world of difference in blocking out the cold in winter and the summer heat. The quality is very high. I definitely recommend them."
"These blackout liners are a must. They have a nice weight to them and provide excellent blockage of the sun. So happy to have finally purchased them. I love them."
"Very easy to attach and appear to be securely attached. Effectively keeps out the light (my panels are in the bedroom. Looks OK from outside, and does not change the look of the panels from the inside. They are a huge improvement over my old vertical blinds."
