The pictures tell the story. Do not let the the visor extended obstruct your rear view mirror. The product is excellent for my onduty use. Blocks sun glare and blocks night time high beam glare from on coming traffic on my patrols. I have not use the tinted sun visor extender driving directly into the sun going down to the east but I will soon. That is another documentation.

Driving to work into the east evening sun. 50% of the sun glare is blocked. Usually wearing quality dark sun glasses im still squinting. The sun visor extender product proved itself. We'll worth the purchase.

Excellent product.

The Joytutus Sun Visor Extender works well in my Toyota Echo. I was a bit worried about having to slide the toothed holder over the front of my sun visor, but the visor is small like the rest of my car. The tightness didn't do damage and it stayed firmly on while I was driving. It's true that monkeying with it while driving was troublesome in the tight spaces involved. But once it was adjusted (I slid it slightly to the right), I was able to successfully use it to shade the (left) driver's side and flipped it back for front shading on the trip home. The best thing: It doesn't reflect the colors of what's behind me! The old extender showed me a riot of shivering colors, which was so distracting. Evidently it wasn't polarized. This one is. Be sure to get the one with the large toothed holder that fits over the TOP of the visor. I noticed different versions that hang from the bottom. That kind kept falling off.

So far, I really like it. It definitely works to cut down sun glare, and at night glare from lights. The directions are not terribly clear for installing, however. I ordered the large since our vehicle windows are pretty large, but it may limit how much you can block from the sides because it’s so large.

Love. It really helps with blocking the sun. The installation was super easy. So worth the money .my only complaint is you have to be careful on how you touch it. fingerprints.

If every state in the Union painted their roads with reflective paint, like they used to, this might be amazing. If you live in a state that does use the better, more expensive, reflective paint, I think it would work. Where I live (IL), I put the visor down and it toned down the car lights beautifully -- I just couldn't see the curbs, the edges of the road, anything. I was petrified for those few seconds that some person was going to walk near me and I wouldn't see them, either. I could have kept the visor to try out when the sun is low and blinding, but the car visor wouldn't stay up out of the way with this additional visor added to it. My husband said it had to go. (We share a car.) It looks well made, it halfway did its job, but I would not recommend it.

Great sun visor bought it to use while driving the bus. Works great!! Quick delivery exactly what I needed

Very easy to install and work very good

My sun visor extension blocks the sun or even just too much brightness without blocking my vision. The clamp needed reinforcing with a rubber band but now it works great. Just have to remember to keep my fingers off of it!

Ça fait la job mais ce n’est sûrement pas la meilleur invention , le plastique est trop souple et risque de se briser dans pas long

Works a treat. Crystal clear so long as you don’t smudge the plastic. Comes with a cleaning cloth.

Es como traer lentes de sol si esta claro su visión pero si es fácil de reparar con ponerle polarizado más oscuro si así lo quiero ver más oscuro

Avec ce dispositif, je n'ai enfin plus de problèmes de conduite lorsque le soleil est bas sur l'horizon. Le seul souci est que, avec les chaussées en mauvais état, l'écran vibre.... Mais on ne peut pas tout avoir !

Awesome
