Zone Tech Side Window Cling On Sun Shades- 2-Pack Mesh Car Pop-Up Non Suction Cups Needed Sunshade

The suction cups were all crushed had to be treated in boiling hot water and washing up liquid to reshape. They do come annoyingly unstuck occasionally. Covers the whole rear window so it's a good size, would be better if it had a storage bag or straps for when not in use and better quality suction cups.

Effective sunshade, but the suckers are pretty poor quality.

Excelente producto. Lo uso para cubrirme del sol en el avion. Facil de instalar y de doblar para guardar

Fits my vehicles' front windows well and provides ample blocking of sunlight! Would buy this again.

Not very good at all. It won't stay on the window and no way to attach it. Pretty useless really

Item received on time and as expected. Unfortunately the suction cups weren't great. I picked up some diaper pins at the dollar store and pinned the shade to my roof. Works great and I have no complaints.

This is a great, light-weight shade that reduces glare while still providing good visibility. When I have my dogs in the car, I actually use a couple more of them to fully cover my side windows and keep the sun off the dogs (yes, they extend forward to the front windows when I do that but the suction cups are strong enough to hold them in place even where they bend to go over the door posts and that just provides more sun protection for the dogs.Suction cups: these are the same suction cups that are used on a variety of auto sun screens and they have generated much discussion whenever they are used. I've actually reviewed them in detail for another sun screen - here's what I said:THE SUCTION CUPS ARE JUST FINE: they ARE lightweight - but then only have to hold up a couple of ounces and they do that quite well; they ARE extremely flexible - but this is a GOOD thing as it enables you to get a better seal when you put them on and makes them easier to remove when you take them off.You do, however, have to do as others have suggested and heat them up in hot water to eliminate any creases that may have appeared during shipping and storage before using them for the first time. Here's what I did:Heat a cup of water until it's VERY hot. I just put a coffee cup of hot water in the microwave for a minute and it was fine. The water doesn't have to be boiling but it won't hurt the suction cups if it is.Put the suction cups in the water for a minute or so. Again, it doesn't hurt to leave them longer but you need to make sure that you leave them in long enough for them to get warm all the way through.Take them out and press them firmly onto a flat surface. Make sure that the cups are completely flattened and don't have any creases in them. Leave them like this until they cool completely.Put the suction cups on the screens and they will hold very well. Mine have been up in my car for four days now and are still firmly attached.Caveat: some people have mentioned the suction cups don't hold when it's cold. I live in Texas so I don't have much opportunity to test that but I believe it's likely to be true: if the suction cups are cold and stiff, they won't flex enough to seal completely. My guess is that if you held them in front of a heater vent for a minute or two or even just held them in your hands long enough to warm them up, they'd hold. Or at least they'd hold as long as the window isn't really cold. At any rate, once the car interior warms up, they should be fine.
