Not for me but works well for blocking sun

Works well for its purpose however it also blocks my view making it too dangerous so I don't even use mine.

It works great to block the sun and still allow a breeze. They are rather dark to see out of though. I just bought spot mirrors to help cover the blind spots.

I love the protection this umbrella provides from the sun. However, The size of this umbrella isn't really useful for two people at once as the website boasts. I got the largest one available and it still isn't quite what I consider large enough for even one person to be covered adequately. The sun shines on my calves if the sun is not directly overhead although I am an average height. I wish there was an extra large so I wouldn't have to worry as much but this umbrella does a great job with my face and shoulders. I'll just have to combine sunblock with my sunblocker umbrella.

I bought these for black out curtains in the light green for my sons room.  they didn't block much sun I current use them as a closet covering in his room.

Not a bad product. Works well. Just fits me but I'm a ham fisted man. Difficult to see in direct sunlight, but okay if you move into the shade.

I bought this screen protector because it looked nice with a case I have. However, working in a garden center and in the sun it was too hard to see the time, or to call someone. If you are a night person only then this will work for you, but outside in the day time it just does not work.

The no-headache part is true. The color and fabric are also very nice. However, the bib is very small. It really doesn't keep the sun out of my eyes. If they make a larger version, I'll buy it because I like it. It's just not very useful. I was looking for something to keep the sun off my face while walking. The search continues.

The previous reviews are correct when they state the shade does not block 88-90% of the sun. We are in the Pacific NW with a low evening sun, and it is our opinion the shade blocks about 50-60% of the sun. Helpful to our problem but not a complete solution. The instructions were not detailed, but the installation was easy to understand, so no problem swapping the chain from one side to the other. Measuring the distance for the holes is critical, as one reviewer indicated. I did swap out the screws as it was installed on a wood pergola. Overall, it is light weight, only 4 pounds, and easy to install, particularly for 2 people.

the fabric is nice and fluid and does the job in blocking the sun.  I wouldn't call it blackout tho. May buy another as the two are a bit stretched for the large window.

Works good, does fog glasses and is not very stretchy. Does not work well with big noses. Kept the sun off my face very well.

perfect for keeping the sun off of me. I think after a wash and dry, it may fit better.

These do the job, but are definitely cut for car windows (with the sloping back end).  I was able to stretch it enough to make it work on my Highlander, but it took a little work and still curves up a little at the bottom because it's been stretched so far..  That being said - it's absolutely the best thing I've found for blocking the sun from my daughter.  It's actually dark enough that I have to be sure to take an extra second to look as I'm backing out of my driveway in the mornings.  I just wish they made an SUV version that would fit a bit better

I used this for a week at the beach and it was great to block the sun.  It does have two windows, but it does not allow much air flow.

This worked out fine for my needs and should last a long time if I don't mistreat it.  It blocks the sun.....also blocks the view so take note of that if it matters to you.

Price was fair and quality decent.  Thank you.

The bill is too small for adequate protection from the sun. I think all it does is to prevent sunlight from entering my eyes, the sides of my face are totally exposed to sunlight and the flap on the back covers my hair, which I deem to be redundant for girls with long hair. I have another hat that definitely does a better job at covering a wider angle of your face.

Material isn't that flimsy which is a plus.

Will have to see how much it keeps the sun off my head.  Umbrellas are too big and block the view for others.  Will try at the next outdoor event (along with sunscreen ofcourse). Will have to be careful when handling the stick and raising the parasol.

I want to start this off with the fact that I am surprised at how well these glasses block out the sun. I have bought similar ones before and they were terrible in this regard. The frames are not that great, when I first took them out of the package I could tell they were definitely a bit too flimsy for comfort--although for the price I'm not surprised or disappointed.
The main issue I have with these are that they actually look a bit too small on. I don't have that large of a head, and they look quite squinted.
The color is also not what I was expecting. They look very nice sky blue in the picture, however they are only slightly tinted blue and it is a much darker blue than the picture looks.

All in all, I don't hate them enough to return them, but I am not as in love with them as I was expecting
