Magnetic Blackout Window Cover 40" x 58" Portable Blackout Curtains for Bedroom, Temporary Black Out Shades Window Privacy Film No Drill Black Out Blinds for Media Room Travel Skylight - Blacks

I was very satisfied with the results. Easy to understand the instructions. Also keeps the room cooler. Would recommend using this product

Total black out effect! It completely blocks the light from coming in. Hopefully I will see a decrease in my electric bill during the hot summer months!

Nice but flimsier than I thought. Just fit the window it was bought for. We have a street light that is very bright but the window is in the shower so this was my best choice & it worked. Take it down in the morning ing put it up at night.

I bought this to fix the light leaking through our blinds, and it honestly made the room pitch dark. I put it up in a few minutes before bed and finally slept through the night without early morning light waking me up. It sticks well and stays in place, even after opening and closing the window. Simple, effective, and feels like a real upgrade for better sleep.

I suffer from migraines, and I put these up in my bedroom over my blinds and put curtains over it so you can't see the blackouts

It was almost dark in our room, but it did not keep the heat out. Our room was still extremely high like it always is.

I have night shift so need to sleep at daytime but the normal curtain does not work, but this did! this is really black and could fit my window easily. Very easy to install and the quality is great. Hopefully it will stay workable in later months.

This is a great window cover, one side is silver to reflect the sunlight, the other side is blackout. It has magic sticker and magnet installer. There are some smell on the cover, but after place it outside for few days it gone. The cover function in excellent, no more daylights in my room
