Absolutely NOT Zero Blackout
346008
I got an 84in in caf color.  This curtain does NOT block 100% light as claimed.  And its not like it does 99% and Im just nitpicking  no, you can see plenty of light coming through the curtain. Maybe 80% blocking at best.  It darkens, but does not provide a total blackout, which is what I want in my bedroom.  I don't know if I expect too much from blackout curtains in general, but when the product description states absolute 0% light, thats what it must deliver.  The only true blackout I was able to find so far was from a pair of ugly curtain liners at Home Depot, so Im starting to suspect the liners would always be  required  I also don't understand the majority of other good reviews reporting total darkness  do other colors deliver the promised blackout?  The relatively high price, considering there is only one panel in the package, adds insult to injury.

Do not order this for a front mount unless you can overhang your window by a few inches (exceeding the frame probably). They don't make them wide enough to actually black out my 36" window. The insulating feature creates a layered effect that puts the blackout feature about an inch away from the window which allows light through the sides. Only truly a black out shade if you install inside window framing to block that side light. Returned it immediately, and wished the seller would include more information for what conditions their blind actually function properly. Thank you amazon for easy returns.

The product description uses the word "blackout" multiple times but these definitely are not blackout curtains. Barely even darkening. I got the "greyish white" and that actually does describe the color perfectly. They have a grey tone to them without being fully grey. But as you can see in my photos, they didn't even remotely block out daylight, even when I layered them with another linen-type curtain. Returned.

I am very disappointed by these, they are not black out curtains by any means. It is no darker in the room than with plastic blinds.

Not quite what I was expecting! I wanted a bedside lamp to use before bed. There are 3 things to note about this light: 1) the 360 degree light that Aukey vaunts is terrible for a bedside lamp (you really need a shade), 2) that damned blue light on the front stays on ALL THE TIME which is annoying when the rest of your bedroom is completely dark and 3) the white light produced by the lamp is far too cold (guide says 2900k but it feels more like 3300k).

In addition, you should note that even if you're able to select the color you want (as it rotates through the colors available) it will be reset as soon as you turn the light off. The light defaults back to white every time.

I want to send it back but then I have to pay shipping and then it's like, "is this worth it?"

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.

I would not consider these "Blackout", but more "Room Darkening".  However, perhaps a darker color would work better.  For the price, you absolutely cannot beat these.  I do get direct sun into our baby's room, so I thought these would be perfect.  While they do block the light, a significant amount still gets through and the room is overall pretty "light".  Definitely NOT dark.  But, as mentioned, for the price, this is a great deal.  If you want the most bang for your buck, I would buy a dark color.  That would probably help with maximum light blocking.

They looks great but not 100% blackout. They help for sure but if you are looking for complete darkness you won't get it from these. But overall I love them!

These function well as curtains, sure. They are maybe 10% better than the non-blackout curtains I already had. 99.9% blackout is a hefty claim and these come nowhere near blackout. Pretty disappointed.

Beautiful curtains, but definitely not blackout curtains!  The curtains allowed a lot of light through.  As someone who works the nightshift and needs curtains to shut out light when I am sleeping during the day, these just don't work.  Too bad though because the material was very soft and the pattern was beautiful.

These didn't really do much for "blacking out"... The room was still very light in the morning. My other blackout curtains have a liner in them and they work really well in terms of keeping rooms dark for sleeping, these are quite thin and I ended up returning them.

You MUST read the directions and you MUST follow the directions.  You can not keep this on your windows 24/7.  You have to take them down before the high noon sun/heat hits your windows. My windows cracked. I knew there was a chance, but because I am a tired, working mom, I was lazy about it.  Now what I thought would be a cheap alternative to darkening my son's room has turned into a $600 job - between window repair and finally opting to purchase the blackout cellular shades.  BUT when this are on your windows, the room will be super duper dark.  Highly recommended if you have other short term needs to darken a room.  If you're a tired parent who needs your kids to sleep during daylight hours but they want darkness, think twice about getting this.  Buy the Home Decorators blackout blinds.  They are not ugly at all.  Bought mine at Home Depot for $120 and it was worth it.  I would've given this zero stars due to my mishap, but I give it 3 b/c it does work for short term purposes.  The directions say this.  I can complain that they need to put it in big letters, but really, I was too tired and desperate to heed the instructions.

I bought these in white and they are definitely NOT blackout. I'd say the darker colors work better for blocking light but if you're looking for true light blocking curtains, don't order white. The fabric is nice for the price though

The light bleeds through during the day. Not Blackout curtains.

I got these in beige for my 2 yr old son's room, for naps. These are in NO way blackout curtains. There is absolutely nothing in the material or backing (there is no backing) that makes them thermal either. They block light as much as a regular curtain. I'm keeping them, because they do look nice, but I've put up cardboard against the window, under the curtain to block light and insulate.

Now these are blackout curtains! The only light that comes in is around the edges. If you close them out or set them back in the window, you will have no light coming in. Worth every penny!

Definitely not a blackout curtain. Material is thin enough that light still gets through so I don't know how well the thermal insulation is either. Other than that, the curtain is a nice color and design.
