Another possible winner - Actually, another winner
It arrived earlier this evening in a bubble wrap Kraft paper bag. Strangely, it came in a package for another model (2 in 1 for day and night with a panel in gray and one in amber) This had, as noted in the description , ONE panel, gray, polarized, apparently Polycarbonate because it is flexible without brittleness, but I'm not a plastics expert. It is 5.25 inches wide X 12.25 inches long and mounts very easily using the push button to adjust it to snugly fit visors up to 7.25 inches wide. I will test it tomorrow and update my review then but it looks as though it will do the job of muting the late afternoon sun glare. The mount does work well to allow it to be easily adjusted to a preferred angle/position. I plan to keep the original padded envelope in which it came for storage in the car...so it shouldn't get scratched by things in the back seat that can scratch plastic. I dinged it one star because it should have had product specific wrapping but it is probably a 4.8 star because using it is intuitive and does not require a consult with a rocket scientist and it seems to be a very useful gadget. On second thought 4.8 is almost 5 stars so I'll round it up.UPDATE (08-29-2019): So it is sunny out and it is in the car. As I thought, it easily fits the visor in my 2010 Prius and, depending on how it's mounted, can either be used in lieu of the car's visor, as a downward extension of the visor to effectively cover the lower part of the windshield and -effectively- block late afternoon sun glare; or, if you want to look really weird, it can be placed a few inches from the tip of your nose so it covers the entire windshield when you look through it. This is great for when the sun glare is so bad and you need something to supplement the polarized sunglasses and don't give a damn what you look like as long as it works to cut that blinding glare. So it works and works well. You'll have to play with it to find out which position works best for you. It's also, at $8.99 + tax, seems to be the least expensive one of its type on Amazon.

Did not fit my car
Had to return it since it would not fit my car. The opening of the clips on both ends of the mount are too narrow to wrap around the both edges of my existing car visor. In addition, the plastic reflective shield is quite flimsy and not rigid.Seller graciously sent me a second item with a different design at no charge. It seems to fit my car and I will be testing it out for performance and durability.

It just took up space.
I had it for awhile before I actually put it in my car so I could not return it. It did nothing. It hung off of my visor so I was constantly hitting it. When I did put it down it was like it wasn't even there. I tried it both with and without my sunglasses on. It made no difference. The tint on it is so light. I can not recommend anyone buy this. If you want one then make sure it has a dark tint.

USELESS!!!!!
Flimsy, lightweight plastic not dark enough to be much help if it could be mounted in a usable position. Didn’t even bother to return it, just threw it away.

Bit Flimsy
The visor is easy enough to install. There is a sizable gap between the holder and the visor itself so the sun can still get you. My biggest disappointment is the flimsiness of the plastic. I don’t handle it roughly but it’s already cracking away from the housing.

Not effective! Not mechanically sound!
Doesn't tilt quickly. Claimed 2 attachments. Found only one attachment. Not effective block sun.

Poorly designed and flimsy
This is really cheap and poorly made. There is a gap between the car visor and the plastic visor which allows sun to go through. It does not work. THe visor is very flimsy......... do not recommend.........
