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.

Great quality, no smell and super easy to put up! Fit my window perfectly, two minute install! Perfect for that space above AC to keep sun out and curtains open! Blackout while sleeping! This is second one I’ve purchased as other has lasted without discoloration in sun and keeps heat out, cold in, vice versa in winter! Well worth money spent!

They’re doing their job, I only give it a 4 star because the sticky thing came off the 1st time I hang it, I have some extra 3m that I am now using and so far its staying up.

The Roller Shade is great and does the Job it’s intended to do. Nice price point, but only Black is at a fair price. Great when you can’t close curtains all the way due to Air Conditioner’s in the window. Prepped/Cleaned window frame with Alcohol - so far adhering well - hope it stays that way.

Please give these a try. Rooms is complete darkness even during mid day. Very easy to install. The roll and clip function is great. I didn't have to cut. Haven't attempted to wash yet but so far so good. Looks great too!

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

Purchased one to see if it works and most definitely does, so got 2 more. Keeps the light out of sun facing windows in the back. Cheap fix compared to other methods. I got black to block all sunlight.
