Bests & Worsts Reviews from Amazon

I have used Eclipse brand, for nine years. So when I needed drafty windows covered, from the extreme cold we're having I did not hesitate to purchase again. But these are AWFUL! Hung them last night, when they arrived and you can see the sun coming through so easily(1st window is my good eclipse thermals, 2nd is these I'm reviewing), how are they energy saving or thermal? I may have to return!
