These are easy to install.  They can NOT be cut to fit even though in one place on the description it says "Trimmable: Yes".  They can NOT be trimmed.  Also, a couple of them came with the bottom portion in pieces but I was able to put them back together and since they are going in rooms to where they are going to stay down 99% of the time, I didn't worry about that.  Had it been for a more visible window, it would have needed replacement.  These are simple, neat, pretty, easy to install and easy to use.  I really like them and ordered more for additional windows now.
