Cling Glare Reducer Sun Shade Side Window Car Curtains UV Rays Visor Protection,Universal Fit Protects from Sun-Rays - for All Year Round Use. Perfect for Road Trips 2-Pack

I thought these were great, but i would take a half star off if I could because they do not last very long. I recently took them on a long trip (~3,000 miles in 7 days.) They were super handy but by the end of the trip they had lost any stickiness and kept falling off the window. Still, they were cheap enough that I just tossed them and ordered another set.

They were no help at all. I got the first one peeled back and applied okay. I didn't have such luck with the second one, getting the back off was unsuccessful. When I peeled it back, it tore the screen part.

I know the title sounds contradictory but here's what I mean: These things cling to the window like eggs cling to teflon. One time, I actually got them to stick to the windshield long enough for me to get out of the car and walk away. But, when I came back, there they were, curled up and laying on the floor. So, I got some double sided tape and taped them to the windshield. That worked better than I expected. Now that the things are affixed to the windshield, they do a good job of reducing the glare of the sun beyond the reach of the sun visors. Note that I said "reducing". To make them more transparent, numerous holes are punched into them. But, the holes are too big and, given that these are typically placed along the top of the windshield, unnecessary to allow for a safe view. Every morning, I head East directly into the rising sun and in the evening, west into the setting sun. These shades have made it possible for me to make the trips without being blinded,so, to that end, they work. But they don't work as advertised.

These work great in my car to block the sun from areas that the visor can't reach. I'm only 5 ft so am affected by afternoon sun both on the front windshield and the driver's side window. Putting a strip in each area has made a huge difference. I recently ordered more to increase the coverage areas. Easy to cut to size and install or remove if needed. Great product.

I bought this product because after we set our clocks back an hour in the Fall the sun is at a lower angle in the afternoons that is blinding. I've either held my left hand up to block the sun when it's shining through the driver's window like that OR flipped my visor to the side. I was looking for something that just stayed there in place without my having to do either of those things---and that would allow me good visibility through it (looking out the driver's window.) This strip does that fairly well. They don't cover a lot of the window (to block the sun as it goes down) but there are two in the package, so I can use them together for better coverage. The one I've used so far has clung to the window perfectly. I took one point off for Easy to Install because I had a hard time pulling the backer off the cling. A small extra amount off the cling would make that easier.

Thin, flimsy window cling, sz 3.5x11.5" - so thin a corner folded over on itself. Not all that much different than good quality clear plastic food wrap. Requires two hands to position on the glass. Black print w/tiny clear dots - similar to honeycomb shape. There is no actual "tint". I chose unwisely - much better off with both a dedicated pair of good quality driving sunglasses (or fitovers) and a ball cap - and always keep them within reach in your vehicle... also keep both sides of your windshield clean & streak free for much less glare.

Bought that a while ago to put up by my review mirror. Couldn't stand the sun blinding me. These work great and aren't peeling off at all. Great price for just what I needed!

It would be nice if products like this provided more specific information. My (totally incorrect) assumption was that these glare blockers would be a greenish static-cling film. Well, they're not - they're actually an opague black film with a pattern of clear dots, to allow filtered light through. The description on Amazon doesn't state that, and you can't tell from the picture. Actually, they would probably work just fine if you buy these things to use as depicted - that is, stick them across the top of your windshield. Alas, what I was looking for was a moveable film that can be put anywhere, including directly in my field of vision - like the pilot's sunblockers from the olden days. And these won't work for that purpose - they obstruct your vision. More specifically, I was hoping I could use one on the inside of a motorcycle helmet visor. DEFINITELY NOT useable for that particular application. From a distance of 30" (let's say, from your eyes to the top of a windshield in a typical car), you can see fairly well through the Glare Blockers, particularly if they're kept above or to the side of where your eyes are focused. But put them across a helmet visor, and you may as well cover it with blackberry jelly, for all you're going to see. So I'm not going to give the product a total write-off. Shame on me for trying to repurpose it. But I AM saying that you shouldn't buy the Glare Blockers unless you intend to use them exactly as shown in the picture.
