Little light peeks thru in upper corners, but don't know how could be avoided. Was a little surprised with the use of double stick tape to hold the track in place, but time will tell if it holds up. They look nice!"

I'd say about 99% blackout - but that 1% tradeoff is about .25 of an inch on the bottom of the shade that is a protective layer so that it gracefully touches the bottom of the window frame. Side rails are a really nice feature that ensures the blind doesn't sway in the wind."

My sister recently purchased two for her home and loved them, but expressed disappointment with the tiny spaces on the sides of the blinds that let light in. (Light always finds a way, it is like water!) I liked the look of hers and was about to purchase an identical one like hers until a phone rep at blinds.com showed me where to go online to find the comfortex one. I wish they would have listed these with the other room darkening shades, as I would have wasted a lot less time and made a better decision I didn't even know about these. They should be in the same category. I loved the idea that I had a solution to the light-leak from the sides with the comfortex. The downfall is that I have to pull hard, very hard, and then lock the shade in when bringing the top all the way up. (I have top down-bottom up feature). My sisters blinds had extra material at the top bar that hung down about an inch so that when the rail was brought up to the top, light would not be able to leak through. Comfortex lacks this important feature and so I have to really pull tight to get the rail to meet the top. I get nervous at having to pull so hard on the string to close the blind close enough to keep light out; as I don't see this string/cord lasting very long. Overall, I have greater light control than my sister and my baby sleeps very well in her room with a bright southern sun shining on her window. BTW- I did not go with the cordless feature, as I read too many negative reviews about it. I would love to hear that they have improved the mechanism to work properly all the time. Maybe have a lock in feature or something. SO there is room for improvement, but it is the best out there as far I can see. Oh! and get samples! I was surprised at the varied colors of white!"

I work the 3rd shift and wanted my room dark for sleeping during the day and these blinds provide exactly what I was looking for. Very satisfied and love the muslin color it matches my walls."

I ordered 4 of them. They are so dark they are incredible. Maybe a speck of light at the two top corners is all I can see. If a light is on in a bedroom, you cannot tell it from the street at night. I was without window coverings in my bedroom for about a month, then after these were put in I just was really unsettled for a couple of nights because I was getting used to the bright lights of the street shining in. But I really wanted a nice blockout shade and this really fits the bill for me. I had liked them in a friend's house, and then when I ordered mine just like his he knew exactly how to put them up. It took us about 2.5 hours to install 4 blockout shades, and 3 faux wood blinds, a total of 7 shades."

Contrary to directions I did not take head rail off to set the side tracks. I just slid them up and pressed into position."
