These cellular shades installed easily and look fantastic. I had NINE windows to treat in a non-primary room which I did not want to spend a fortune on. These totally fit the bill giving privacy and light control with the top down bottom up feature. The crank/ratchet system was unfamiliar to me but they work. The head rail is vinyl and the fabric seems like paper versus a non-woven polyester like most brand cellular shades; my finger went through the back of one by accident very easily puncturing it! These are perfect for me, since I live alone, but I would not recommend for a family with kids of any age to have their hands on these, they would not last but they are a fantastic value in low traffic applications. I hope they keep the cold air back this winter, but don't think they will be as effective as name brand cellular shades - will find out soon--.
