Don't even think about ironing these.  They need to be put in the dryer with a wet towel.  They look nice though.  Not very good at blocking sunlight.

Obviously, it's tough to buy sunglasses without being able to try them one.  In this case, they are oversized and cheap plastic, but they do cut down on the sunlight.

These curtains claim to block 85-95% of light, that's just not the case for the lighter color varieties. From my judgement they're blocking far less than half the light during the day. We plan to return them right away.

These do a wonderful job blocking sunlight while also looking very nice- unlike other light blocking curtains that look rough.

The curtains block light very well!  They are not as square and even as they could be.  Fortunately, the light blocking was the main purpose for buying them, and they meet that need perfectly.

I'm a beach lifeguard. Having dark lenses is not good for observation so i like a lighter color but these are to light. Not great for bright sun. Also the mirror coating isn't very robust. Could be better but the price is nice.

Just in case the photo fooled you, these curtains are beige with dark brown (maybe a touch of olive drab) leaves, with dark gold accents. They're quite pretty, and they look classy as window dressings.

When the sun is low, they block out almost all the light; however, in bright, direct sunlight, light still shows through. They're great for me though--I don't mind some light showing through during the day, but if you're looking for the kind of blackout curtains that'll keep your room very dark during the day, maybe go for something darker.

They are not as light as their full size counterparts so they blocked too much light. Since they were a little longer than I wanted I folded over the top and hung them on rings so they'd be easier to open and close and that adjustment worked well. They gave me a kitchen-y look which I really didn't want. I also ordered one pair too many so they'll go back.

Not the nicest looking curtain, but blocks out the light beautifully.  If they were less shiny, they would be awesome.

They don't block as much light as I would like. I do like the color!  They really should be a bit bigger too...

I bought this to put up as a privacy screen and to block some light at night given off by my neighbor's outdoor lights.  It doesn't really do either very well.  You can for the most part see right through it, although it does block direct visibility during the day.  At night, it does absolutely nothing to even slightly filter light coming through.  The blinds look nice, but functionally, not so great.  I've only had them up for a few weeks, so I can't speak to quality issues that others are reporting.  I would not recommend.

These are OK.  They fit well and look great.  They keep the wind and dirt out of my eyes.  My biggest complaint is that the lenses do not get dark enough.  They offer little protection from the sun itself and are about useless if you're riding into the sun.

The curtains are a pretty color but it doesn't completely block out light. It needs to be a little thicker.

I like the way they look, but strangely these sunglasses are not protecting from the sun, there is no way to look in the sun with them. Also its not possible to put them on the head for example, I have same size aviator model too, way better design.

I want to love these. They are so much more attractive than the film, and those roll up shades. BUT, they simply don't block as much sunlight. They are super easy to put on and take off. No annoying suction cups. They really do cling. But I can see my son squinting and turning his head away from the sun that's coming through, and I can't help but wish they were darker and blocked more light...

Not quite as "room darkening" as I was expecting. Therefore not as insulating against the afternoon sun as I was hoping for. they are really good looking panels.

Pro: They look nice and do not absorb much, if any, water (which prevents mold)

Con: They indent very easily and the indent doesn't come out.
