These curtains do the job of making the room dark but it is a little difficult to cut out the right size rectangle from such a large piece of fabric. Overall good quality though.

These work so well to cut out light! But they were a hassle to assemble. (Although I think that’s just my issue)Even came with measuring tape which was nice!

I bought this for our camper. Keeps out the sun. Easy to cut and install

Liked that we could cut it to fit the window and there was enough for two windows in the rooms we used in our beach rental that the kids slept in. The shades worked great to block out light but the sticky dots sent to hang them should not be used on walls. When we removed the shades it pulled the paint off. Not good when you are renting a home!

Do your research - you MUST NOT sick these TO any double-paned window! I still recommend these shades, but NOT for use as directed. Here's the problem: they can ruin the seals on your windows - days, weeks or months later your window will start fogging up. I read about this problem on line, and I even called a window manufacturing plant near us. The defective material over heats up your window too much, and can weaken the seal, causing it to fail at a later date. NO ONE in the window industry recommends sticking these to windows. HERE'S HOW TO USE THESE: We still wanted to prevent bright sun from coming in, so we strung a piece of string a few inches from the window and bought little clothes line clamps to hang the material down a few inches away from the window, leaving an air space. Then we took the material down in the morning, and put it back up at night, so that the sunshine all day was not still being bounced back to the window. They did not function as black-out shades that way, but they did darken the room and prevent direct sun from hitting the bed in the morning, so we were very happy with the effect. Rig the material up so that there is several inches of air space between the material and your window, take the material down as soon as you wake up, and it works great. Further suggestions: ALL AIR B&B and VBRO owners with windows that are not shaded should forbid this material. Use it wisely, and you will be happy. This material should NOT be sold as a product to stick TO the window!!

I was able to cut enough pieces to fit all windows in a conversion van. It needs more sticky pieces that will last longer than once to use.

To hard go me to put up. Maybe for someone with more patience.

We used this blackout material to keep the sun off of our twins on a 16 hour car ride by custom cutting the curtain to fit my car windows and it was fantastic! I fashioned it with a bamboo rod stapled into the bottom so I could roll it up and use clips for it to stay at the top and when the sun was too warm or we needed them to nap, I would undo the clips and it would block the sun out perfectly!We also used it to cover the windows at our vacation house so the bedroom would be dark for them to go to bed -- worked like a charm!! I highly recommend getting it if you have babies or you want your room when traveling to be SUPER dark
