ZONETECH Cling Glare Reducer Sun Shade Side Window Sunshades Car Curtains UV Rays Visor Protection Universal Fit Protects from Sun- for All Year Round Use. Perfect for Road Trips (4 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.

So mad I wasted my money on this! Total rip-off. The two 'curtains' are tiny! Don't know how I missed the fact they are so little. If that weren't bad enough, they didn't 'cling' thoroughly and worse of all they didn't block any sun or glare!!! They couldn't have cost more than 25 cents to produce and I wasted $9.00 of my hard earned money on them. Can't believe Amazon sells this product.

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.

When installed properly, and used for the proper application these are great. Unfortunately the description and application on the product page are very misleading. For example "EASY TO INSTALL - The Zone Tech cling-on sun shade is easy to install. Just stick on the windshield." NO! This has to be carefully applied using something like a plastic credit card, or you will have a mess. "EASY TO STORE - The Zone Tech cling-on sun shade is removable and can be repositioned. Furthermore its reusable property allows you to either keep it on the windshield for an extended period of time or remove it after each use." Again, not true. This can not be just easily removed after each use - not what this product is. Once it is removed from its backing it is very thin tape that is difficult to store or re-use. Better descriptions and instructions would make this a useful product.

I’m short and need something to block the sun below the level of the visor. These are seriously a complete waste of money. Super thin, and started curling up around all the edges within a day of putting on the glass. After a few days, it fell right off into a curled dry roll. (My windshield had been cleaned appropriately beforehand.) They don’t feel like typical window clings feel, more of a thin cheap cellophane. I threw them out. Not “quality” as the title claims. At all.

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!
