I like the fact that this is a bottom up as well as a top down shade. Perfect for my situation plus it gives much more flexibility as a shade. I rated it 4 stars because the description was not clear as to how much casing distance is required for an inside mount you need at least 1 34 of an inch if you are mounting the brackets my screwing to the under side of the casement. If you can mount the bracket to the back of the casement then normal casements will work. I could not do this because I have replacement windows and that would mean drilling into the window frame. I solved the problem by cutting a strip of 14 inch thick piece of oak 1 34 x width of inside window measurement. Screwing this to the casing then affixing the shade mounting brackets to the oak strip. Sound complicated but it took ten minutes. Think about it, you’ll understand it. 

The quality of the shade is excellent. They move up and down very smoothly and stay were you place them. Overall I am very pleased.
