The shade looks very nice and classy and has also fitted perfectly. The manual could be a little more detail and I have looked on the Internet a video installation of a competing product before the penny dropped that you have to push a few centimeters above the sidebars.
The mechanism is a little stiff and locked at the bottom is not optimal one, so that the blind habit has over the night 1-2cm up to slides and a clearer light gap can be seen. At least that is our experience from the first weeks of use.
