LazBlinds 100% Blackout Roller Shades, No Tools No Drill Cordless Blinds for Windows, Thermal Insulated UV Protection Privacy Window Shades for Bedroom (36''W x 72''H, Black)OEKO-TEX STANDARD 100

These blinds solved my light blocking problem. I already had blinds in the room and didn’t want curtains. I was able to install these behind my current blinds with ease. Now I can roll them down for complete light blocking (when my grandbaby is here) or roll up and use my regular blinds for light control. They were easy to install. I measured my window, laid the material on my floor, measured with the black side up, marked with a silver marker and cut carefully. I took a picture before and after but the after picture looks like a lot of light is coming in, it really isn’t but my phone brightened the picture. You could also add some small sticky hook and loop to the sides if you want it to lay completely flat, that would provide complete darkness.

These blinds are awesome!!! Great for night time in my son’s room who has an air conditioner so u can’t really shut the curtains. These block out any light and go right behind the blinds perfect! And he’s been sleeping longer and better! The same for my room. Total game changer and super easy to install.100% worth purchase!!

Works as advertised. Used in RV. Wife secured shade with thumbtacks (her Idea). I didn't like the Velcro install as it will pull off of the valance if the shade is removed. The shade was a little narrow to wrap around the valance. I'll try a different way to secure. Otherwise, it worked ok.

This product is basically like buying some black fabric, cutting it to size and taping it up with some double back tape and then having a handy way to roll the fabric up. It’s very basic and simple and works well for people who have window treatments and need something really simple. Having said that It’s definitely not high-end and not 100% perfect but it’s a great price for a simple solution.

I was looking for something outside the box to display my decals for craft shows. This is perfect! The velcro attached to my tent and rain won't hurt it. Plus I only have to carefully roll up the blind and everything is packed up for the next show. Perfect!!!

These are great for blocking out light. However, for the price paid, they are very thin. The front looks like curtain material, but the back looks like a black trash bag. I like my bedroom to be totally dark, and these really worked at keeping the morning sun out. I placed them behind my curtain. You attach Velcro to your window trim and to the black side of the curtain. I did not cut mine vertically because I wanted it to overlap onto the frame to block more light. I leave mine down but if you want to open you have to roll it up and place the clips to hold it. I give 2 stars for the material but 5 stars for blocking out the light.Cordless Blinds for Windows, Thermal Insulated UV Protection Privacy Window Shades for Bedroom (36''W x 72''H, Beige)

I bought four packs of this product. Delivery was on time and the packaging was fine. Unfortunately, one of the bags was already open and it was missing a clip and part of the Velcro strap. Through Amazon, I was guided through the menu to request the missing parts, up to the point where I had to go to the manufacturer's website for support. Unfortunately, the email address provided there does not work, so I decided to write here. If the manufacturer reads this and sends me the missing parts, I would be willing to give more stars, because the product itself is very good and functional. The service, however, is miserable

Works great, set it up in like 2 minutes and now I can use my projector during the day. Materials a little weird feeling but thats just my opinion still a great product
