I like the insert a lot, and it appears to satisfy my needs. It fits really, really snug. So snug I have trouble removing it because I have to place in inside the window case very close to the window rather to the are on interior edge of window as seen in your video. I need to do this because blinds are install on outer edge ( interior side edge)of window. I am trying to decide what to do. I can't use blinds if inserts are installed.
