Review on 🌙 Portable Blackout Curtain with Window Suction Cups (66-inch Length x 51-inch Width) - Temporary Room Darkening Shades for Nursery, Bedroom, Dorm Room - Travel Window Cover by Bishnu Bush

This item costs more than others here, but you can compare the weight to see if this fabric is heavier than others. The quality of the fabric and the suction cups is excellent. We have plantation blinds to allow them to fit under the blinds and out of view, maintaining the look and decor of the space. Very good protection from the hot sun. If you have a window that opens up and down, you can open the window without removing it. My window opens horizontally and the suction cups blocked it so it had to be removed if I wanted to fully open the window. For that reason it really serves the purpose I bought it for but other than that it's a great product.
