Does the job as blackout curtains - just a little light is let is around the edges.  The fabric around the grommets at the top is becoming frayed after washing one time.  Not too noticeable, but for the price I expected them to last longer, especially when I washed them according to the instructions.

Not black out curtains! But still very nice

My husband is an incredibly light sleeper--the slightest noise or sound bothers him. He already uses ear plugs and an eye mask to sleep, but I thought these blackout curtains could assist him in getting a good night's rest. First, the good news. These curtains do exactly what they promise they block out light one hundred percent. They are thick and although we haven't hit the hottest days of the summer, I think they will help to keep the cool air in the room and the hot air out.
My only complaint is the appearance and that is the reason for the reduction of 1 star. The curtains are thick by necessity (see keeping light out completely and insulation properties), but the thickness makes the curtains look unappealing and the thickness of the curtain looks cheap.
BUT...these curtains do exactly what is promised and for that, I am willing to sacrifice a bit on appearance.
I received this product at a discount in exchange for my unbiased review, but I would gladly pay full price.

Work well as a blackout but not exactly energy efficient in the summertime.  When the sun heats up the dark fabric you aren't gaining much.  It would work better with a liner, which I had intended to use, but I have since added blinds to all of my windows and now use these only to blackout the room.

The curtains are certainly blackout, and the grommets are nice.  Furthermore, it's really great that these curtains come in so many different lengths.  This combination of features is something hard to find in stores.

That said, the color/material aren't particularly stunning.  I got the chocolate color, and they weren't really a great shade of brown - they didn't match any of the wood flooring or furniture I had in my room.  The feel of the curtains also isn't inspiring.

If you need blackout curtains and want grommets (which definitely make your curtains easier to open/close) and want a length that is shorter than 84", these are a great option.  I searched for quite a while and these were the only curtains I found with these features.  But if you also care about style, I don't think you'll be happy (though maybe other colors are better).  Personally, I preferred blackout but didn't require it, so I'll be returning these and will be getting non-blackout curtains with a style/feel I like better.

nice curtain -- but NOT a blackout curtain.  As the other reviewers write (and i should have paid attention to) this is not as advertised -- it's called a blackout curtain, but light comes through, and i have to buy another to put in the nursery :(

Decent curtains. I got the beige. As long as it's not morning light, the curtains will black out the room. I was looking for some curtains to keep my bedroom dark, and help keep the cold air from coming in though the drafty window. It does help retain the heat in my bedroom, but it doesn't block the morning light, which is what I would prefer. Maybe if I had ordered a darker color, it would have worked better.

But, decent price for two panels, blocks out most light and helps retain the temperature in rooms.

Color and length was as expected and they look great.

They are NOT true blackout curtains. I work night shifts and needed blackout curtains so I could sleep during the day after I got home from work.  I am very familiar with blackout shades and curtains and what kind of quality to expect; when I am traveling for work and stay in hotels I use the blackout curtains to sleep through the day.  At home, I already have shades on my windows and bought these to block out the remaining light coming into the room.  These curtains are better than others I've seen but while they block out some light it's not what I was expecting or needing and certainly are not true blackout curtains - if I had hung JUST the curtains with no shades underneath there would be far too much light still filtering in.  They do the job well enough and I am keeping them but by themselves I would have to return them.

These work excellently for blocking out light and they look pretty nice as well. You'll need to hang the curtains so they cover the border well beyond the window in all directions, otherwise lots of light will creep in around the curtains.

These curtains do a great job of blocking out almost all of the coming in through the windows.  Also helps dampen outside noise.  If you are looking for curtains to greatly reduce the amount of light, these are the ones you want.  You can't go wrong for the price.  They don't feel as thick as I expected but still work wonderfully.

It gets the job done.  Since you can't turn off any sections of the light off I suggest you get some blackout diffusers to create the lighting effect you want.

By no means are they blackout curtains, but luckily they look super cute in the nursery. I just wish it was a little darker.

These do block out a lot of light, but these do not block out all outside light. A good amount of light still shines through all four side of the window. Irritating when you work nights. I have these curtains up as well as a homemade window covering, which covers the window's glass, blocking out the light from even entering the window (After insatlling these). I used about $20 of crafting paper and im getting the same effect of the EZ Blackout, i just cant open my windows now. LOL. For me, these curtains are for an aded layer of blackout (they are good, just not good enough). I also bought the "EZ Blackout" just haven't installed them yet.

These are nice "blackout" curtains for a bedroom. They keep the light out and I'm a night time worker so blocking out the sun during the day is very important to me. I don't really see a purpose for the tan extensions at the bottom.

We got these for our nursery, and although we were happy with the blackout aspect, it wasn't why we bought them. We have a giant double window in the room, and these things do truly black out the room.

We've bought other curtains from Amazon which claim to be "blackout" and they're a LONG, LONG way from Blackout. Not these. If you're just wanting good, classy looking blue curtains. These work. If you're wanting blackout curtains? These work.

Overall works well, but there was a small hole in one of the panels which kind of defeats the purpose of buying blackout curtains.

Bought these to hang with "No. 918 Callie Paisley Heathered Print Curtain Panel, 40 by 95-Inch, Lapis". They match perfectly. My only real complaint is that that these curtains are not lined in any way. When bright light is behind them, I can practically see straight through which makes me worry a bit about privacy. Luckily, they are hung in my livingroom and the most show the neighbors will get is whatever my children are watching on the tv. Would be nice if they blocked out a little more of the light though.
