Review on Coavas Blackout Window Film No Glue 100% Light Blocking For Day Sleep, Privacy Static Cling For Home Security And Aquarium, Frosted Black 35.6 X 118 Inches by Sharmake Shuram

Not what I expected. It worked great and did the job of blacking out the window and light. I would give it 5 stars for effectiveness and thickness. Unfortunately, the material was not easy to cut with a knife while on the window (so user difficulty gives it 4 stars).I wanted this item for a small long window. Because of the shape of the window I wanted to trim off the extra while the product was on the window. It is not like contact paper and did not work well.it is not a very forgiving material. However, it is a good product otherwise- but probably for standard size windows and those that can measure and cut better than I.
