I'm slowly replacing the old roller blinds on my second level with these shades. I love the richness of the color and the ease of installation. With the mounting brackets these were just a *little* too big, so I skipped using the brackets and swapped out the screws with larger ones I had from an IKEA kit and screwed them into the top of the window frame. It worked perfectly and there's no way to tell I didn't follow the instructions properly.
