It's ok I suppose, not long enough, not deep enough and not dense enough, sun glare can still be experienced though not as bad as without it.

I enjoy using this sunshade. I see people smiling at it when I am parked in public parking lots. It has little suction cups to help it stay up, but they seem to let go as soon as it gets about 90 or more. Still does the job.

It does keep the car cool, and on long drives protects me from sun damage to the left side of my body.  Nice because I can take it off easily when I don't need it.

No problems - do not use for night vision and keep out of suns rays

I am really enjoying it since I get headaches sometimes, and especially at night when my eyes get tired. It has helped out alot. Not too dark but just dark enough I think. Went on just fine and wipes off pretty good if it gets dirty.

Definitely isn't the easiest screen protector I've ever had to apply and ANY dust or other particles WILL show up and create bubbles that cannot be squeegeed out so make sure to clean your screen well and apply in a clean area. Once applied, it does as well as you can hope to reduce glare for a protector at this price. It is good, not great, and for my intended purpose for this protector (being able to read at the beach) it will be good enough for now.

Bought this for one of my cell phones. Anti glare works good in sun light. Colors on the cell phone looks a little grainy, but colors kinda pop a little more too. Had the phone for a while and the shield out lasted the cell phone and did not were out.

Overall this thing is pretty good, but I thought I'd make note of something I haven't seen mentioned in the other reviews:

When I look through the screen protector while wearing any kind of polarized sunglasses, it creates a dark brown/rainbow pattern that makes it very hard to read the screen.  I guess this is because the plastic of the screen protector is not really that smooth.  Without sunglasses, it looks fine.

In any case, if you're planning on using this in the car or outdoors and you wear sunglasses, you might want to be aware of this.

This item is easy to install and use. The reason for the 3 star rating is it doesn't completely do what it says. Other reviewers have noted that it didn't change anything. My experience did not find that to be the case all of the time. When the sun was REALLY bright it made no noticeable difference - I know that is the point of getting it - but at that point I did not know if it was the item that failed or if I was just "sun blind" and couldn't pick up the difference.  I still left the back on as a protector without the hood - but do put the hood on if for nothing else but protection when carrying the camera out of the bag.

I used this product on my camera  for the last ten days and hundreds of vacation photos. It reduced sun glare enough to make the lcd more viewable than it had been, but in the brightest conditions the lcd was no more useable than it had been before I installed this product on it. Given it's ease of installation, lcd screen protection, and improvement in glare reduction, I give it a 4 rating and I am glad that I am using it.

I'm still trying to get the hat dent and crease free, but it is good at shading the face from the sun.

Got tired of losing my Oakley flak jackets, so got these.  The polarization isn't as good as the Oakley's but it's still good.  Definitely reduces glare on water and while driving.

The fit is a bit snug on my head and can get uncomfortable for me at times.  But everyone always tells me I have a big head from my hat size.

The nose pads are a little low, which cause the sun glasses to sit higher on my face then I would like.  it's not obnoxious or tacky, just a little to high for my liking and what I'm used to.  Also, while the lenses themselves are bright and reflective, they're not 100% mirrored.  I go to school in florida so I'm always walking in bug crowds outside in the bright sun, and I'm always wondering if people walking the opposite way I am can see that I'm staring at them or not.  Good sunglasses but not the best I've experienced (as far as cheap sun glasses go).  I will wait to see how well they hold up before I decided whether or not I'll buy again.

Does slightly reduce the screen's resolution, but because of the anti-glare quality I'm happier overall with my phone's appearance. Not having a reflection really helps, especially in sunny situations.

It works find because the sunlight is blocked , but not your vision since the visor is not pulled down when in use.

I've had bluBlocker before and I remember them being more helpful in the sun but I lived in CA at the time.  I now live in AZ and the sun is really bright and I was hoping that they would help more than they do.  They are still better than regular sunglasses but still not how I remember them.

Creates more glare, but other than that it's a relatively good product. If put on quickly, the screen protector will cause major bubbles that will be difficult to remove, so it may take a few tries to apply correctly. It's kept my screen clean which was its intended purpose so I can't complain.
